4.Useage
Dichloromethane has the advantages of strong dissolving ability and low toxicity. It is widely used in the production of safe film film, polycarbonate, and the rest as paint solvent, metal degreasing agent, aerosol spray agent, polyurethane foaming agent, mold release agent and paint removal agent.
Dichloromethane, a colorless liquid, is used as a reaction medium in the pharmaceutical industry to prepare ampicillin, oxypicillin and avanamycin.
It is also used as foaming agent and metal cleaning agent in film production, petroleum dewaxing solvent, aerosol propellant, organic synthetic extraction agent, polyurethane and other foam plastics.
Dichloromethane is mainly used in film production and medicine in China.
Among them, the consumption of film production accounts for 50% of the total consumption, the consumption of medicine accounts for 20%, the consumption of cleaning agent and chemical industry accounts for 20%, and the consumption of other aspects accounts for 10%.
Dichloromethane is also used as a refrigerant carrier in industrial refrigeration systems, but it is very harmful, producing highly toxic phosphogas in contact with open or hot objects.
Moisture in the air can hydrolyze to form a trace of hydrogen chloride, light can also promote hydrolysis and increase the corrosion of metals.
Used for grain fumigation and refrigeration of low pressure freezers and air conditioning units.
Used as an auxiliary foaming agent in the production of polyether urane foam and as a foaming agent for extrudingpolysulfone foam.
Methylene chloride is also used to make decaffeinated coffee.
Coffee is first boiled to dissolve the caffeine and float it on the surface, then dichloromethane is used to remove the caffeine.
