Formic acid [64-18-6] HCOOH, M r 46.03, is a colorless liquid with a pungent odor, which is completely miscible with water and many polar solvents but only partially miscible with hydrocarbons. Formic acid derived its name from the red ant, Formica rufa, in which it was discovered around 1670. Formic acid has been detected in the poison or defense systems of ants, bees, and other insects and also of cnidarians.

Formic acid is used primarily in dyeing, in the textile and leather industries; in rubber production; and as an intermediate in the chemical and pharmaceutical industries. The use of formic acid as an aid in the ensilage of green forage has increased sharply.

The worldwide production of formic acid is about 260 000 t/a in 1987 and 390 000 t/a in 1995 [1]. Formic acid is produced by hydrolysis of methyl formate or formamide or from its salts. In addition, formic acid is a byproduct of acetic acid production by liquid-phase oxidation of hydrocarbons.
