Dichloromethane 100%

Dichloromethane (CH2Cl2) is a compound in which two hydrogen atoms in the methane molecule are replaced by chlorine. It is a colorless, transparent, heavier than water, volatile liquid that has an ether-like odor and sweetness, does not burn, but forms an explosive mixture when mixed with high concentrations of oxygen. Dichloromethane is slightly soluble in water and miscible with most commonly used organic solvents. It is also miscible with other chlorine-containing solvents, ethyl ether, ethanol and N, n-dimethylformamide in any proportion. At room temperature, dichloromethane is insoluble in liquid ammonia, and can be quickly dissolved in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, and ethyl acetoacetate. Phase Chemicalbook pair density 1.3266(20/4°C). Melting point -95.1°C. Boiling point 40°C. Non-combustible low boiling point solvent, commonly used to replace flammable petroleum ether, ether, etc., and can be used as dental local anesthetic, refrigerant and fire extinguishing agent. Spontaneous ignition point 640°C. Viscosity (20°C) 0.43mPa·s. Refractive index nD(20°C)1.4244. The critical temperature is 237°C and the critical pressure is 6.0795MPa. After pyrolysis, HCl and trace phosgene are produced, which are heated with water for a long time to form formaldehyde and HCl. Further chlorination gives CHCl3 and CCl4.
