Formic acid is an natural substance with the chemical system HCOOH and a molecular weight of 46.03 , usually recognized as formic acid, which is the easiest carboxylic acid. A colorless liquid with a pungent odor. Formic acid is a susceptible electrolyte, however its aqueous answer is weakly acidic and corrosive, which can stimulate pores and skin blistering. It is typically determined in the secretions of bees, positive ants, and caterpillars. It is an natural chemical uncooked material, additionally used as a disinfectant and preservative.
Formic acid was once first developed via J. J. -L. Guy-Lussac is organized through decomposition of oxalic acid. In 1855~1856, M. Berthelaw immediately organized sodium formate with sodium hydroxide and carbon monoxide, and T. Gold-Schmidt was once the first to put together formic acid from sodium formate through hydrolysis. This approach started out to be used in industrial manufacturing in Europe in 1896 and is nevertheless used in small batch production. In 1980, Scientific Design Corporation, Bethlehem Steel Company and Leonard Company efficiently developed a technique for the carbonylation of methanol to produce formic acid, and a plant with an annual output of 20 thousand heaps of formic acid was once put into operation. In addition, formic acid can additionally be recovered from the spinoff of oxidation of acetic acid from mild oil.
In hydrocarbon and gaseous state, formic acid takes place in the shape of dimers certain with the aid of hydrogen bonding. In the gaseous state, hydrogen bonding outcomes in a giant deviation between the formic acid fuel and the best fuel equation of state. Liquid and strong formic acid consists of a non-stop flow of formic acid molecules sure via hydrogen bonding. Due to the one of a kind shape of formic acid, one of its hydrogen atoms is at once related to the carboxyl group. It can additionally be considered as a hydroxyformaldehyde.
