Main uses:
Formic acid is a basic organic chemical raw material, which is widely used in pesticide, leather, dye, medicine and rubber industries.
Formic acid can be directly used in fabric processing, leather making, textile printing and dyeing and storage of green feed, and can also be used as metal surface treatment agent, rubber additive and industrial solvent. In organic synthesis, it is used to synthesize various pharmaceutical intermediates of formate, ammonium nitrogen fertilizer and formamide.
The specific classification is as follows:
(1) pharmaceutical industry: caffeine, metamizole, aminopyrine, aminophylline, theobromine borneol, vitamin B 1, metronidazole and mebendazole.
(2) Pesticide industry: triadimefon, triadimefon, tricyclazole, triazophos, triazophos, paclobutrazol, uniconazole, insecticidal ether, dicofol, writing purine, etc.
(3) Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethylformamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, epoxidized soybean oil, octyl epoxidized soybean oil, pivaloyl chloride, paint stripper, phenolic resin, pickled steel plate, etc.
(4) Leather industry: leather tanning agents, deashing agents and neutralizers.
(5) Rubber industry: natural rubber coagulant.
(6) Others: Dyeing mordants, dyes for fiber and paper, treating agents, plasticizers, food preservatives and animal feed additives can also be manufactured.
(7) Preparation of co Chemical formula: HCOOH (concentrated H2SO4 catalysis) heating =CO+H2O.
