Relative molecular weight: 84.93
At room temperature and pressure is colorless transparent volatile liquid, with irritating odor similar to ether: melting point: -95.1℃, boiling point: 39.8℃, relative density: 1.3266 (80/4℃) is dissolved in about 50 times water, soluble in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, ethyl acetoacetate, cyclohexamine, mixed with other chlorinated hydrocarbon solvents ethanol, ether and N, n-dimethylformamide

Dichloromethane has the advantages of strong solubility and low toxicity, and is widely used in the manufacture of safe film and polycarbonate. The rest used as coating solvent, metal degreaser aerosol spray agent, polyurethane foaming agent, release agent, paint stripper. Dichloromethane as a colorless liquid bar, in the pharmaceutical industry as a reaction medium, used for the preparation of ampicillin, oxicillin and vanguard amycin, etc. It is also used as solvent in film production, petroleum dewaxing solvent, aerosol propellant, organic synthetic extraction agent, foaming agent and metal cleaning agent for polyurethane and other foam plastics production.
