There is one situation in which aspartame is known to be harmful. Aspartame should not be consumed by people suffering from a genetic disorder called phenylketonuria. A person suffering from this disorder is unable to create the enzyme that changes phenylalanine into tyrosine. As a result, phenylalanine accumulates in the body. People with phenylketonuria must follow a low phenylalanine diet to avoid brain damage. Since aspartame breakdown produces phenylalanine, the sweetener must be avoided. Formic acid (HCO2H), also called methanoic acid, is the simplest carboxylic acid. Formic acid was first isolated by the distillation of ant bodies and was named after the Latin formica, meaning ant Since formic acid is an antibacterial agent, it's frequently added to the feed of farm animals to prevent the growth of bacteria. It's occasionally used as a preservative in human foods. The chemical is also used to create artificial flavors for foods and drinks and artificial scents for perfumes. In addition, formic acid is used in leather tanning, in the processing of textiles and paper, and in the conversion of latex from the rubber tree into rubber. The acid is used in an appropriate concentration for each of these jobs.Formic acid is readily metabolized and eliminated by the body. Nonetheless, some chronic effects have been documented. Some animal experiments have demonstrated it to be a mutagen, and chronic exposure may cause liver or kidney damage. Another possibility with chronic exposure is development of a skin allergy that manifests upon re-exposure to the chemical. The principal use of formic acid is as a preservative and antibacterial agent in livestock feed. When sprayed on fresh hay or other silage, it arrests certain decay processes and causes the feed to retain its nutritive value longer, and so it is widely used to preserve winter feed for cattle. In the poultry industry, it is sometimes added to feed to kill Salmonella bacteria.

Since formic acid slowly decomposes when boiled, distillation must be done at low temperature and in near vacuum (25 °C at 40 mm Hg).[1] As early as the fifteenth century, some alchemists and naturalists were aware that ant hills gave off an acidic vapor. In 1671, English naturalist John Ray became the first person to describe the isolation of formic acid by the distillation of large numbers of ants. These insects secrete the substance for attack and defense purposes. Thus the name "formic acid" was coined from the Latin word for ant, formica.

Chemical Nomenclature and Chemical Formulas

Concentrated solutions of formic acid are corrosive to human skin, as well as nose, mouth and eyes and also slowly decompose to form water and carbon monoxide, which can cause an explosion from pressure buildup in a sealed container. Adding a dehydrating agent will also generate large amounts of carbon monoxide, a deadly gas that is impossible to detect with human senses. Formic acid is not inherently very toxic if ingested, though long exposure to it by any means can cause chronic bodily effects. It is especially important that formic acid is kept away from the eyes, as it readily damages the optic nerve and can cause permanent blindness. FORMIC ACID reacts exothmerically with all bases, both organic (for example, the amines) and inorganic. Reacts with active metals to form gaseous hydrogen and a metal salt

Its formula is CH2O2 or HCOOH.In nature, it is found in the stings and bites of many insects of the order Hymenoptera, including bees and ants. It is also a significant combustion product resulting from alternative fueled vehicles burning methanol (and ethanol, if contaminated with water) when mixed with gasoline. Its name comes from the Latin word for ant, formica, referring to its early isolation by the distillation of ant bodies. A chemical compound such as a salt from the neutralization of formic acid with a base, or an ester derived from formic acid, is referred to as formate (or methanoate). The formate ion has the formula HCOO−. Properties Formic acid is miscible with water and most polar organic solvents, and somewhat soluble in hydrocarbons. In hydrocarbons and in the vapor phase, it actually consists of hydrogen-bonded dimers rather than individual molecules. In the gas phase, this hydrogen-bonding results in severe deviations from the ideal gas law. Liquid and solid formic acid consists of an effectively infinite network of hydrogen-bonded formic acid molecules.Formic acid shares most of the chemical properties of other carboxylic acids, although under normal conditions it will not form either an acyl chloride or an acid anhydride. Until very recently, all attempts to form either of these derivatives have resulted in carbon monoxide instead. It has now been shown that the anhydride may be produced by reaction of formyl fluoride with sodium formate at −78°C, and the chloride by passing HCl into a solution of 1-formimidazole in monochloromethane at −60°C. Heat can also cause formic acid to decompose to carbon monoxide and water. Formic acid shares some of the reducing properties of aldehydes.Formic acid is unique among the carboxylic acids in its ability to participate in addition reactions with alkenes. Formic acids and alkenes readily react to form formate esters. In the presence of certain acids, including sulfuric and hydrofluoric acids, however, a variant of the Koch reaction takes place instead, and formic acid adds to the alkene to produce a larger carboxylic acid.Most simple formate salts are water- soluble. History As early as the 15th century, some alchemists and naturalists were aware that ant hills gave off an acidic vapor. The first person to describe the isolation of this substance (by the distillation of large numbers of dead ants) was the English naturalist John Ray, in 1671. Ants secrete the formic acid for attack and defense purposes. Formic acid was first synthesized from hydrocyanic acid by the French chemist Joseph Gay-Lussac. In 1855, another French chemist, Marcellin Berthelot, developed a synthesis from carbon monoxide that is similar to that used today.In the chemical industry, formic acid was long considered a chemical compound of only minor industrial interest. In the late-1960s, however, significant quantities of it became available as a byproduct of acetic acid production. It now finds increasing use as a preservative and antibacterial in livestock feed. Production A significant amount of formic acid is produced as a byproduct in the manufacture of other chemicals, especially acetic acid. This production is insufficient to meet the present demand for formic acid, and some formic acid must be produced for its own sake.When methanol and carbon monoxide are combined in the presence of a strong base, the formic acid derivative methyl formate results, according to the chemical equation CH3OH + CO → HCOOCH3 In industry, this reaction is performed in the liquid phase at elevated pressure. Typical reaction conditions are 80°C and 40 atm. The most widely-used base is sodium methoxide. Hydrolysis of the methyl formate produces formic acid: HCOOCH3 + H2O → HCOOH + CH3OH Direct hydrolysis of methanol requires a large excess of water to proceed efficiently, and some producers perform it by an indirect route by first reacting the methyl formate with ammonia to produce formamide, and then hydrolyzing the formamide with sulfuric acid to produce formic acid: HCOOCH3 + NH3 → HCONH2 + CH3OH HCONH2 + H2O + ½H2SO4 → HCOOH + ½ (NH4)2SO4 This technique has problems of its own, particularly disposing of the ammonium sulfate byproduct, so some manufacturers have recently developed energy efficient means of separating formic acid from the large excess amount of water used in direct hydrolysis. In one of these processes (used by BASF) the formic acid is removed from the water via liquid extraction with an organic base.In the laboratory formic acid can be obtained by heating oxalic acid in anhydrous glycerol and extraction by steam distillation. Another preparation (which must be performed under a fume hood) is the acid hydrolysis of ethyl isonitrile using HCl solution. C2H5NC + 2H2O → C2H5NH2 + HCOOH The isonitrile being obtained by reacting ethyl amine with chloroform (note that the fume hood is required because of the overpoweringly objectionable odour of the isonitrile). Uses The principal use of formic acid is as a preservative and antibacterial agent in livestock feed. When sprayed on fresh hay or other silage, it arrests certain decay processes and causes the feed to retain its nutritive value longer, and so it is widely used to preserve winter feed for cattle. In the poultry industry, it is sometimes added to feed to kill salmonella bacteria. Other uses: It is used to process organic latex (sap) into raw rubber. Beekeepers use formic acid as a miticide against the Varroa mite.It is of minor importance in the textile industry and for the tanning of leather.Some formate esters are artificial flavorings or perfumes.It is the active ingredient in some brands of household limescale remover. In synthetic organic chemistry, formic acid is often used as a source of hydride ion. The Eschweiler-Clarke reaction and the Leuckart-Wallach reaction are examples of this application. It is also used as a source of hydrogen in transfer hydrogenation.In the laboratory formic acid is also used as source for carbon monoxide, which is set free by the addition of sulfuric acid. Formic acid is also a source for a formyl group for example in the formylation of metylaniline to N-methylformanilide in toluene. Fuel cells that use modified formic acid are promising. Safety The principal danger from formic acid is from skin or eye contact with liquid formic acid or with the concentrated vapors. Any of these exposure routes can cause severe chemical burns, and eye exposure can result in permanent eye damage. Inhaled vapors may similarly cause irritation or burns in the respiratory tract. Since carbon monoxide may be also be present in formic acid vapors, care should be taken wherever large quantities of formic acid fumes are present. The US OSHA Permissible Exposure Level ( PEL) of formic acid vapor in the work environment is 5 parts per million parts of air ( ppm).Formic acid is readily metabolized and eliminated by the body. Nonetheless, some chronic effects have been documented. Some animal experiments have demonstrated it to be a mutagen, and chronic exposure may cause liver or kidney damage. Another possibility with chronic exposure is development of a skin allergy that manifests upon re-exposure to the chemical.The hazards of solutions of formic acid depend on the concentration.

We have a machine that makes rubber sheets. During the process of making rubber sheets from rubber milk, we have to add formic acid to the milk. Is formic acid dangerous to humans?Formic acid occurs naturally in the venom of some ants and bees. Formate, the conjugate base of formic acid, also occurs naturally in bodily fluids following methanol poisoning. formic acid, formic acid direct from Huanghua Pengfa Chemical Co. in China (Mainland) I will argue against any of your opinions.

Chemical and physical properties of Formic acid. Chemical Properties of Formic acid (CAS 64-18-6) Formic acid is a stronger acid than acetic acid. This is because the methyl group is electron donating or electron releasing compared to hydrogen in the conjugate base of acetic acid , which destabilizes.. The principal danger from formic acid is from skin or eye contact with liquid formic acid or with the concentrated vapors. Any of these exposure routes can cause severe chemical burns, and eye exposure can result in permanent eye damage. Inhaled vapors may similarly cause irritation or burns in the respiratory tract. Since carbon monoxide may also be present in formic acid vapors, care should be taken wherever large quantities of formic acid fumes are present. The U.S. OSHA Permissible Exposure Level (PEL) of formic acid vapor in the work environment is five parts per million parts of air (ppm).

  2. The acid is different from the chelating agent and is selected from the group consisting of glycolic acid, citric acid, lactic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid..
  3. Formic Acid also is known as methanoic acid, is the simplest carboxylic acid. It is having the formula CH2O2. Formic Acid produced industrially as a byproduct in the manufacture of other chemicals
  4. The stinging venom of red imported fire ants (Solenopsis invicuta) contains alkaloids and some proteins but no formic acid. A fire ant bites to grab hold of a person's skin, then tucks its abdomen under its body so that the stinger can reach the skin and inject its chemicals. The ant then withdraws its stinger, rotates a short distance and stings again, repeating the process until it has formed a circle of stings.
  5. translation and definition formic acid, English-Russian Dictionary online. In addition, the laboratory confirmed the presence of high levels of manganese and formic acid
  6. Formic acid is found in the sprayed venom of some ants and the secretions of some stinging nettles. The acid is dangerous at high concentrations but has important uses
  7. Formic acid (HCO2H), also called methanoic acid, the simplest of the carboxylic acids, used in processing textiles and leather. Formic acid was first isolated from certain ants and was named after the Latin formica, meaning “ant.” It is made by the action of sulfuric acid upon sodium formate, which is produced from carbon monoxide and sodium hydroxide.

The pKa of formic acid (HCOOH) is 3.744. Since this is not less than -1.74 it is not a strong acid. Chemical formula for formic acid is HCOOH. It is an organic acid compound Wörterbuch Englisch ↔ Deutsch: formic acid. Übersetzung 1 - 50 von 1046 >> Formic acid is a source of hydride ion in synthetic organic chemistry, as in the Eschweiler-Clarke and Leuckart-Wallach reactions. It is also a useful component of the mobile phase in reversed-phase high-performance liquid chromatography (RP-HPLC) for peptides, proteins, and intact viruses.Methanol is made inside our bodies from normal metabolic processes. It also enters the body from fruits and vegetables and their juices. In addition, humans produce methanol as well as aspartic acid and phenylalanine from the breakdown of aspartame, an artificial sweetener. Methanol is toxic, but most of us don't encounter enough of the chemical to be harmed.In industry, this reaction is performed in the liquid phase at elevated pressure. Typical reaction conditions are 80°C and 40 atmospheres (atm) pressure. The most widely used base is sodium methoxide. Hydrolysis of the methyl formate produces formic acid:

Formic acid can dissolve with water in any proportion and form azeotropic mixture. Formic acid can dissolve nylon, polycarbonate and other macromolecule compounds, but insoluble polyvinyl chloride formic acid Formic acid is a by-product, of the production of levulinic acid from hydroxymethylfurfural. This C-1 compound is formed in equimolar ratio in comparison to levulinic acid Top synonym for formic acid (other word for formic acid) is formate. formic acid. synonyms - similar meaning - 21.

Consequently, acetic acid is a weaker acid than formic acid. Similarly in formic acid there is no alkyl group and hence no inductive effect takes place Although formic acid is easily metabolized and eliminated, it can have toxic effects. Methanol metabolism produces formic acid and formaldehyde, which are responsible for the optic nerve damage that results from methanol poisoning. Chronic exposure in humans may cause kidney damage and skin allergies in some people. Formic acid, systematically named methanoic acid, is the simplest carboxylic acid. The chemical formula is HCOOH or HCO 2 H. It is an important intermediate in chemical synthesis and occurs.. In the laboratory, formic acid can be obtained by heating oxalic acid in anhydrous glycerol, extracting the product by steam distillation. Another preparation (which must be performed under a fume hood) is the acid hydrolysis of ethyl isonitrile using hydrochloric acid solution.[1][2] Calculated pH values of common acids and bases for 1, 10, and 100 mmol/L (valid for standard conditions at 25°C, 1 atm; acidity constants are taken from here

Formic Acid (HCOOH) - Formic acid is the simplest carboxylic acid with the chemical formula HCOOH. Visit BYJU'S to understand the properties, structure and its uses Formic acid , systematically named methanoic acid , is the simplest carboxylic acid , and has the chemical formula HCOOH Can formic acid from the carpenter ants I have in the basement be causing a couple of small patches of missing hair on my cat with underlying glistening and red skin? My cat is always snooping around in the basement, which is leaky and wet and has ants. I'm always spraying the basement and she comes up itching all the time. Formic acid (methanoic acid, HCOOH) is a colorless liquid with a sharp odor. It is soluble in water, various alcohols, acetone and ether. Most applications require formic acid in concentrations of 85..

The use of aspartame is controversial. However, health agencies say that a person’s normal exposure to methanol, including the methanol produced from aspartame, is too low to cause health problems. They also say that aspartame is safe, provided the Acceptable Daily Intake (ADI) of 40 mg/kg body weight is not exceeded. There are claims that aspartame makes the symptoms of certain health disorders worse, but at the moment there is no scientific evidence to support these claims.

Scientists say that the production of formic acid from methanol in humans only becomes a problem if there is a large amount of methanol in the body, as there would be in methanol poisoning. In this situation, enough formic acid could be made to create a condition called acidosis. Symptoms of acidosis may include vision problems, blindness, memory loss, confusion, seizures, coma, low blood pressure, and cardiac arrest.Formic acid is also prepared in the form of its esters by treatment of carbon monoxide with an alcohol such as methanol (methyl alcohol) in the presence of a catalyst.

Formic acid (systematic name methanoic acid) is the simplest carboxylic acid. Its formula is HCOOH or CH2O2. In nature, it is found in the stings and bites of many insects of the order Hymenoptera, particularly ants 1.

Researchers at the University of Texas have discovered an interesting phenomenon in relation to the ants. When a crazy ant is stung by a fire ant, the crazy ant curls its abdomen upwards to its mouth, secretes formic acid from its venom gland, and then rubs the secretion over its body. The process is shown in the video above. The formic acid protects the crazy ant from the fire ant's venom. Formic acid (also called methanoic acid) is the simplest carboxylic acid. Formic acid is a colorless liquid having a highly pungent, penetrating odor[3] at room temperature Formic acid. Section 1 - Chemical Product and Company Identification. MSDS Name: Formic acid.
