Application：Dichloromethane has the advantages of strong solubility and low toxicity. It is widely used in the manufacture of safety film and polycarbonate. The rest are used as coating solvent, metal degreasing agent, gas smoke spray agent, polyurethane foaming agent, release agent and paint remover.
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 for film production accounts for 50% of the total consumption, medicine accounts for 20%, cleaning agent and chemical industry accounts for 20% of the total consumption, and other aspects account for 10%. Dichloromethane is also used as a refrigerant in industrial refrigeration systems, but it is very harmful. It can produce highly toxic phosgene when in contact with open fire or hot objects. In case of humid air, it can hydrolyze to produce trace hydrogen chloride, and light can also promote hydrolysis and enhance its corrosivity to metals。
