1、 Overview:
Illustrative formula:Molecular weight of HCHO: 30.00Common name: Forrest Marin
Properties: This product is colorless, pungent and malodorous liquid. It is easy to polymerize at low temperature to form white precipitate insoluble in water; The relative density of 37% solution is 1.075-1.085, the boiling point is 101 ℃, and 9-13% methanol is often added as polymerization inhibitor for industrial products. Water solubility; It is flammable and has the risk of combustion in case of fire and heat source; The flash point of 37% formaldehyde solution without formaldehyde is 85 ℃; Violent reaction in contact with oxidant; It has high toxicity, strong irritation and corrosivity. It belongs to other corrosive articles, and the UN number is un1198
IIPurpose:
It is one of the important organic chemical raw materials. It is widely used in the preparation of polyformaldehyde resin, phenolic resin, urea formaldehyde resin, melamine resin, nylon fiber and other organic synthesis industries.
