Formic Acid
Formic acid is one of the basic organic chemical raw materials, which is widely used in pesticide, leather, dye, medicine, rubber and other industries. Formic acid can be directly used in fabric processing, leather tanning, textile printing and dyeing and storage of green fodder, as well as as metal surface treatment agent, rubber auxiliary agent and industrial solvent. In organic synthesis, it is used to synthesize various formate esters, acridine dyes and formamide series of pharmaceutical intermediates. The specific classification is as follows:
1. Pharmaceutical industry: caffeine, analgin, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole, and mebendazole.
2. Pesticide industry: triadimefon, triadimefon, tricyclazole, triazophos, paclobutrazol, Uniconazole, insecticide, dicofol, etc.
3. Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethylformamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, epoxy soybean oil, epoxy octyl soybean oleate, tervaleryl chloride, paint remover, phenolic resin, pickling steel plate, etc.
4. Leather industry: tanning agent, deliming agent and neutralizer of leather.
5. Rubber industry: natural rubber coagulant.
6. Others: It can also manufacture printing and dyeing mordant, dyeing agent, treatment agent, plasticizer, food preservation and animal feed additive for fiber and paper.
7. Make CO. Chemical formula: HCOOH=(concentrated H2SO4 catalysis) heating=CO+H2O
8. Reducing agent. Determination of arsenic, bismuth, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver and zinc. Determination of cerium, rhenium and tungsten. Examine aromatic primary and secondary amines. Solvent for determination of relative molecular weight and crystallization. Determination of methoxy. Used as fixative in microanalysis. Manufacture of formates.
9. Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the formate generated 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.
