Industrila Grade Methylene chloride/DichloromethaneI purity 99.99% CAS No.: 75-09-2
Introduction:
It is Colorless liquid,with characteristic odor.Relative density D4 201.326, melting point-96.7℃, Boiling point: 40.4℃, If it is mixed with high concentrated Oxygen, the explosive mixture is formed but it is not inflammable. It is one of the low-boiling-Point industrial solvents that have small ltoxicity, no inflammable.It has good solubility for many resin, waxand fat, soluble in water slightly, easy soluble in other chloro solvent, ethoxyethane and ethanol. Dichloromethane can take place hydrolysis with water in a certain temperature.

Application:
1.Dichloromethane has the advantages of strong solubility and low toxicity. It is widely used in the manufacture of safe film and polycarbonate. The rest are used as paint solvent, metal degreaser, smoke spray, polyurethane foaming agent, demoulding agent and paint stripper.
2.Dichloromethane, a colorless liquid, is used as a reaction medium in the pharmaceutical industry for the preparation of ampicillin, benzylpenicillin and cephalosporin. It is also used as solvent, oil dewaxing solvent, aerosol propellant, organic synthesis extractant, polyurethane and other foaming agents and metal cleaning agents in film production.
3.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% of the total consumption, cleaning agent and chemical industry accounts for 20% of the total consumption, and other aspects account for 10%. Methylene dichloride is also used as a refrigerant in industrial refrigeration systems, but it is very harmful. When it comes into contact with open fire or hot objects, it can produce highly toxic phosgene. When exposed to humid air, hydrogen chloride can be hydrolyzed to form trace amounts. Illumination can also promote hydrolysis and enhance the corrosiveness of metals.
4.It is used for grain fumigation and refrigeration of low-pressure refrigerators and air conditioners.
5.It is used as auxiliary foaming agent in the production of polyether-type urethane foam plastics and as foaming agent for extruded polysulfone foam plastics.
6.Methylene dichloride is also used to make decaffeinated coffee. Coffee is first boiled to dissolve caffeine and float on the surface, then decaffeinated with dichloromethane.
