Formic acid is an organic compound with a chemical formula of HCOOH and a molecular weight of 46.03. It is commonly known as formic acid and is the simplest carboxylic acid. It is a colorless liquid with a pungent odor. Formic acid is a weak electrolyte, but its aqueous solution is weakly acidic and highly corrosive, which can stimulate skin blisters. Usually found in the secretions of bees, some ants and caterpillars. It is an organic chemical raw material, also used as a disinfectant and antiseptic.

Formic acid Usage:
1. Pharmaceutical industry: It can be used in the processing of caffeine, analgin, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole, and mebendazole.
2. Pesticide industry: It can be used in the processing of tricloxazone, triadimefon, tricyclazole, triamazole, triazophos, paclobutrazol, uniconazole, dimechlor, and dicofol.
3. Chemical industry: raw materials for the manufacture of various formate, formamide, pentaerythritol, neopentyl glycol, epoxy soybean oil, epoxy soybean octyl, pivaloyl chloride, paint remover, and phenolic resin.
4. Leather industry: used as tanning agent, deliming agent and neutralizing agent for leather.
5. Rubber industry: used in the processing of natural rubber coagulant and the manufacture of rubber anti-aging agent.
6. The laboratory produces CO. Chemical reaction formula:
8. Determination of cerium, rhenium and tungsten. Checks for aromatic primary and secondary amines and methoxyl groups. Determine the relative molecular mass and solvent methoxyl of the crystallization. Used as a fixative in microscopic analysis.
9. Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the formed formate can be dissolved in water, so it can be used as a chemical cleaning agent. Formic acid does not contain chloride ions and can be used for cleaning equipment containing stainless steel materials. [2]
10. It is used to prepare food flavors such as apple, papaya, jackfruit, bread, cheese, cheese, cream, etc., as well as flavors for whiskey and rum. The concentration in the final flavored food is about 1~18 mg/kg [3].
11. Others: It can also manufacture printing and dyeing mordants, fiber and paper dyes, treatment agents, plasticizers, food preservation, animal feed additives and reducing agents, etc
