Description
Formic acid is an organic compound with the chemical formula HCOOH and a molecular weight of 46.03. It is commonly known as formic acid and is the simplest carboxylic acid. A colorless liquid with a pungent odor. Formic acid is a weak electrolyte, but its aqueous solution is weakly acidic and highly corrosive, and can stimulate skin blistering. Usually found in the secretions of bees, some ants and caterpillars. It is an organic chemical raw material and is also used as a disinfectant and preservative.
1. Pharmaceutical industry: It can be used for the processing of caffeine, metamizole, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole and mebendazole.
2. Pesticide industry: It can be used for the processing of triazole, triadimefon, tricyclazole, triazole, triazophos, paclobutrazol, uniconazole, insecticidal ether and dicofol.
3. Chemical industry: raw materials for manufacturing various formates, formamide, pentaerythritol, neopentyl glycol, epoxidized soybean oil, epoxidized octyl soybean oleate, pivaloyl chloride, paint stripper, 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 coagulants and the manufacture of rubber antioxidants.
6. Preparation of CO in the laboratory. Chemical reaction formula:
8. Determination of cerium, rhenium and tungsten. Test for aromatic primary amines, secondary amines, and methoxy groups. Determine the relative molecular mass and crystallization solvent methoxyl groups. Used as a fixative in microscopic analysis.
9. Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts. The generated formate can be dissolved in water and can therefore 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.
10. Used to prepare apple, papaya, jackfruit, bread, cheese, cheese, cream and other edible flavors as well as whiskey and rum flavors. The concentration in the final flavored food is approximately 1~18 mg/kg.
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.
