Methylene Chlorid
Uses of Methylene Chlorid
The most important use of dichloromethane is solvent. Dichloromethane has a strong solubility, low boiling point and relatively the lowest toxicity and relatively the best reaction inertia, making it the most used organic solvent in the organic synthesis, with almost the same significance of water in inorganic chemistry. It is largely used in the manufacture of safe film, polycarbonate, the rest used as paint solvents, metal degreasing agent, gas aerosol spray, polyurethane foam, mold release agent, paint remover.
It is also used as the reaction medium in the pharmaceutical industry for the preparation of ampicillin, ampicillin and cephalosporin.
Dichloromethane is inert because of the stereoscopic electron effect, and usually does not participate in the chemical reaction. But under certain conditions it can also participate in the reaction. Explosion accident occurred in industry because of the generation of diazomethane methane when residual dichloromethane and sodium azide reacted in N, N-dimethyl formamide.
Dichloromethane is mainly used in film production and medicine in China. Film production accounts for 50% of the total consumption, medicine accounts for 20%, the cleaning agent and chemical industry accounts for 20%, and others accounts for 10%.
CAS NO: 75-09-2
Methylene chlorid has the advantages of strong dissolving power and low toxicity. It is much used in the manufacture of safe films and polycarbonate, and the rest is used as coating solvents, metal degreasers, gas aerosol propellants, polyurethane foaming agents, release agents, and paint removers.
Methylene chlorid is a colorless liquid and is used in the pharmaceutical industry as a reaction medium for the preparation of ampicillin, oxybenzylicillin, and cephalosporin, etc. It is also used as a solvent in film production, an oil dewaxing solvent, an aerosol propellant, an organic synthetic extracting agent, a foaming agent for producing foamed plastics such as polyurethanes, and a metal cleaner.
Methylene chlorid is mainly used in film production and medicine in China. Film production accounts for 50% of the total consumption, medicine accounts for 20%, the cleaning agent and chemical industry accounts for 20%, and others accounts for 10%. Methylene chlorid is also used as a refrigerant in industrial refrigeration systems, but it is hazardous and can produce highly toxic phosgene when in contact with open flames or hot objects. In the case of moist air, it can be hydrolyzed to generate traces of hydrogen chloride. Light can also promote its hydrolysis and increase the corrosion capacity of metal.
Methylene chlorid is used for grain fumigation and refrigeration of low pressure refrigerators and air conditioners. It is used as an auxiliary foaming agent in the production of polyether urethane foams and as a blowing agent for extruded polysulfone foams. [4]
Methylene chlorid is also used to make decaffeinated coffee. The coffee is first cooked so that caffeine, which is then removed by using methylene chlorid, dissolves and floats on the surface.We have methylene chloride for sale，please contact us.
