Product Description

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 antsand 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.

Formic acid is also prepared in the form of its esters by treatment of carbon monoxidewith an alcohol such as methanol (methyl alcohol) in the presence of a catalyst.

Formic acid is not a typical carboxylic acid; it is distinguished by its acid strength, its failure to form an anhydride, and its reactivity as a reducing agent-a property due to the CHO group, which imparts some of the character of an aldehyde.

The methyl and ethyl esters of formic acid are commercially produced. Concentrated sulfuric aciddehydrates formic acid to carbon monoxide.

Usage:-

Formic acid has been shown to be an effective treatment against warts and is marketed for that purpose by Meda AB under the trade name Vårtfri (="Wart free") in Sweden and Endwarts internationally.

Formic acid is a source for a formyl group for example in the formylation of methylaniline to N-methylformanilide in toluene. In synthetic organic chemistry, formic acid is often used as a source of hydride ion. 

Formic acid is also used in place of mineral acids for various cleaning products, such as limescale remover and toilet bowl cleaner. Some formate esters are artificial flavorings or perfumes. 

Beekeepers use formic acid as a miticide against the tracheal mite (Acarapis woodi) and the Varroa mite. The use of formic acid in fuel cells is also under investigation.


Precautions
Depending on how concentrated it is, formic acid can either be unnoticeable or very dangerous. Through the course of our typical interaction with this chemical, we are exposed only to very low concentrations. Because of this, there is very little to fear. If exposed at high concentrations, however, there are many dangerous side effects that can occur.

The most dangerous aspect of the formic acid is its highly corrosive nature when in a concentrated form. Because it is so corrosive, highly concentrated amounts of formic acid can lead to serious injury if it is inhaled, swallowed or touched directly.

This includes ulcers, nausea, burns, blisters and extreme discomfort around the affected area. Although it is not likely except under special situations, high concentrations of formic acid should be avoided altogether.
