Product Description

Product description

Dichloromethane, a colorless transparent liquid, has a pungent odor similar to ether. Insoluble in water, soluble in ethanol and ether. It is a nonflammable low boiling solvent and is often used to replace flammable petroleum ether, ether, etc. Dichloromethane has the advantages of strong solubility and low toxicity. It is widely used in the manufacture of safety film and polycarbonate, and the rest is used as paint solvent, metal degreaser, aerosol spray, polyurethane foaming agent, mold release agent, paint release agent, and also can be used to make decaffeinated coffee.

Application

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

Dichloromethane is a colorless liquid used as a reaction medium in the pharmaceutical industry to prepare ampicillin, hydroxybenzylpenicillin, and cephalosporin; It is also used as solvent in film production, petroleum dewaxing solvent, aerosol propellant, organic synthetic extractant, foaming agent for polyurethane and other foam plastics production and metal cleaning agent.

Dichloromethane is mainly used in film production and pharmaceutical fields in China. Among them, the consumption used for film production accounts for 50% of the total consumption, the pharmaceutical sector accounts for 20% of the total consumption, the 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 highly harmful and can produce highly toxic phosgene when in contact with open flames or hot objects. When encountering humid air, it can hydrolyze to produce trace amounts of hydrogen chloride, and light can also promote hydrolysis and enhance its corrosiveness to metals.

Used for grain fumigation and refrigeration of low-pressure refrigerators and air conditioning devices. It is used as auxiliary foaming agent in the production of polyether urethane foam and as foaming agent for extruded polysulfone foam.

Dichloromethane is still a substance used to make decaffeinated coffee. Coffee is first steamed to dissolve and float the caffeine on the surface, and then dichloromethane is used to remove the caffeine.
