Dichloromethane has the advantages of strong solubility and low toxicity. It is widely used in the manufacture of safety film and polycarbonate. The rest is used as coating solvent, metal degreaser, aerosol spray agent, polyurethane foaming agent, demoulding agent and paint stripper.

Dichloromethane is a colorless liquid, which is used as reaction medium in pharmaceutical industry to prepare ampicillin, hydroxybenzylpenicillin and vancomycin; It is also used as solvent, oil dewaxing solvent, aerosol propellant, organic synthesis extractant, polyurethane foaming agent and metal cleaning agent in film production.

Dichloromethane is mainly used in film production and medicine in China. Among them, the consumption of film production accounted for 50% of the total consumption, medicine accounted for 20% of the total consumption, detergent and chemical industry accounted for 20% of the total consumption, and other aspects accounted for 10%. Dichloromethane is also used as a refrigerant in industrial refrigeration system, but it is very harmful. When it comes into contact with open fire or hot objects, it can produce highly toxic phosgene. It can hydrolyze to produce trace hydrogen chloride in humid air, and light can also promote the hydrolysis and enhance the corrosiveness to metals.

It is used for grain fumigation and refrigeration of low pressure freezer and air conditioner. It is used as auxiliary foaming agent in the production of polyether urethane foam and as a foaming agent for extruding polysulfone foam plastics.

Dichloromethane is also used to make decaffeinated coffee. Coffee is cooked to dissolve caffeine and float on the surface, then decaffeinated with dichloromethane.
