Formic acid is one of basic organic chemical raw materials, widely used in pesticide, leather, dyestuff, medicine and rubber industries. Formic acid can be used directly in the storage of fabric processing, tanning, textile dyeing and green feed, as well as metal surface treating agents, rubber auxiliaries and industrial solvents. In organic synthesis, the synthesis of various formic acid esters, acridine dyes and methamide series pharmaceutical intermediates.
Organic acids are highly corrosive. Flammable, can be mixed with water, ethanol, ether and glycerin, and most of the polar organic solvents are soluble in hydrocarbon.
