Methylene Chloride Dichloromethane CAS 75-09-2 99.99%

Product Description:

CAS NO： 75-09-2, formula CH2Cl2. Methylene Chloride is a kind of colorless, transparent liquid, 

Dichloromethane is a halogenated hydrocarbon with two chlorine atoms connected to the same carbon, so it has many properties of halogenated hydrocarbons, such as M-X exchange, oxidative addition, nucleophilic substitution reaction, etc. Many transition metals can react with dichloride, which is why dichloromethane is rarely used as a solvent in metal-catalyzed reactions. Phosphine compounds have strong nucleophilicity and can undergo nucleophilic substitution reactions with methylene chloride to obtain quaternary phosphonium salt compounds. In addition, phosphorus anion compounds can also undergo a nucleophilic substitution reaction with methylene chloride to obtain a product in which two phosphorus atoms react with a methylene group at the same time.

Product Application: 

Dichloromethane (DCM) has the advantages of strong solubility and low toxicity, and is widely used in the production of safe film, polycarbonate, as well as in other applications such as paint Solvents, metal degreasers, smoke aerosol sprays, polyurethane foam agents, mold release agents, paint strippers, and more.

Dichloromethane is a colorless liquid, used as a reaction medium in the pharmaceutical industry for the preparation of ampicillin, hydroxybenzyl penicillin, cephalosporin, etc. It is also used as a solvent in film production, a wax remover in petroleum, a propellant in aerosols, an organic synthesis extractant, a foaming agent in polyurethane foam production, a metal cleaner, and more. In China, dichloromethane is mainly used in film production and the pharmaceutical industry, with film production accounting for 50% of total consumption, pharmaceuticals for 20%, cleaners and chemical industry for 20%, and other applications for 10%.

Widely used in the manufacture of safety film film, polycarbonate, the rest is used as paint solvent, metal degreasing agent, gas smoke spray agent, polyurethane foaming agent, mold release agent, paint removal agent.

Other solutions include Methylene Chloride,  Isopropyl Alcohol, Glacial Acetic Acid. Welcome to contact for more information.
