1、 Overview:
Indicative formula: HCOOH molecular weight: 46.03 common name: formic acid
Properties: formic acid is the simplest carboxylic acid. Colorless and pungent liquid. Weak electrolyte, melting point 8.6 ℃, boiling point 100.8 ℃. It is highly acidic, corrosive and can stimulate skin blistering. It is found in the secretions of certain ants and caterpillars. It is an organic chemical raw material and also used as disinfectant and preservative. Formic acid is combustible, and it is dangerous to burn in case of fire and heat source; The flash point is 68.9 ℃; It is acidic and reductive, and reacts violently in contact with alkali and oxidant; It is strongly irritating and corrosive. It is an acidic and corrosive substance. The number of hazardous chemicals is 81101 and the UN number is un1779.
2、 Purpose:
Formic acid is one of the basic organic chemical raw materials, which is used to make chemicals, rubber coagulant, textile, printing and dyeing, electroplating and so on. Formic acid is one of the basic raw materials of organic chemical industry. It is widely used in pesticide, leather, medicine, rubber, printing and dyeing, chemical raw materials and other industries. The chemical industry is used to produce ammonia formate, xylyl ammonia, various formates, antioxidant, etc.
