Formic acid 85%
Formic acid, also known as formic acid, has the molecular formula HCOOH. Formic acid is colorless, has a pungent odor, and is corrosive. Humans will foam after contact. Formic acid has both acid and aldehyde properties. In the chemical industry, formic acid is used in rubber, medicine, dyes, and leather industries.
The main purpose
Formic acid is one of the basic organic chemical raw materials and is widely used in pesticide, leather, dye, medicine and rubber industries. Formic acid can be used directly in fabric processing, leather tanning, textile printing and dyeing and green fodder storage. It can also be used as a metal surface treatment agent, rubber auxiliary and industrial solvent. In organic synthesis, it is used to synthesize various formate, acridine dyes and formamide series of pharmaceutical intermediates. The specific classification is as follows:
Pharmaceutical industry: Caffeine, Analgin, Aminopyrine, Aminophylline, Theobromine, Borneol, Vitamin B1, Metronidazole, Mebendazole.
Pesticide industry: Fenmeining, Triadimefon, Tricyclazole, Triazole, Triazophos, Paclobutrazol, Uniconazole, Tetrafen, Dicofol, etc.
Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethyl formamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, epoxy soybean oil, epoxy soybean oil Octyl acid, pivaloyl chloride, paint remover, phenolic resin, pickled steel plate, etc.
Leather industry: leather tanning agent, deliming agent and neutralizer.
Rubber industry: natural rubber coagulant.
Others: It can also manufacture printing and dyeing mordant, dyeing agent for fiber and paper, treating agent, plasticizer, food preservation and animal feed additives.
Make CO. Chemical formula: HCOOH=(concentrated H2SO4 catalysis) heating=CO+H2O
reducing agent. Determination of arsenic, bismuth, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver and zinc. Verification of cerium, rhenium and tungsten. Test aromatic primary and secondary amines. Determine the relative molecular mass and crystallization solvent. Determine the methoxy group. Used as a fixative in microscopic analysis. Manufacturing formates.
.Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the generated 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.
Hazardous characteristics: flammable; its vapor and air can form a sexual mixture, which can cause combustion when exposed to open flames and high heat energy. Contact with strong oxidants can cause chemical reactions. It is highly corrosive.
Hazardous combustion products: carbon monoxide
Extinguishing agent: alcohol-resistant foam, dry powder, carbon dioxide.
Precautions for fire fighting: Fire fighters must wear full protective clothing and oxygen breathing apparatus to extinguish the fire. Use water to keep the fire container cool, and use water spray to protect the personnel who prevent leakage.
