Uses :
Dichloromethane has the advantages of strong solubility and low toxicity, and is widely used in Manufacture of safety film film, polycarbonate, the rest are used as paint solvent, metal degreasing agent, aerosol propellant, polyurethane foaming agent, mold release agent, paint stripper.
Dichloromethane is a colorless liquid used as a reaction medium in the pharmaceutical industry for the preparation of ampicillin, amoxicillin and cephalosporin, etc.; also used as a solvent in film production, petroleum dewaxing solvent, aerosol propellant, organic synthesis Extraction agent, foaming agent and metal cleaning agent for the production of foamed plastics such as polyurethane.
Dichloromethane is mainly used in film production and pharmaceutical fields in China. Among them, the consumption for film production accounts for 50% of the total consumption, the pharmaceutical industry accounts for 20% of the total consumption, the cleaning agent and chemical industry consumption 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 and can produce highly toxic phosgene when it comes into contact with open flames or hot objects. In case of humid air, it can be hydrolyzed to generate a small amount of hydrogen chloride, and light can also promote hydrolysis and increase the corrosiveness to metals.
For grain fumigation and refrigeration of low-pressure freezers and air-conditioning units. It is used as an auxiliary blowing agent in the production of polyether urethane foam, and as a blowing agent for extruded polysulfone foam.
Dichloromethane is also the substance used to make decaffeinated coffee. The coffee is first boiled to dissolve the caffeine and float to the surface, and then Dichloromethane is used to remove the caffeine.
Packaging and storage:
250KG barrels or ISO TANK can be used.
