Products Description of Dichloromethane CAS#75-09-2

Dichloromethane is a compound formed by replacing two hydrogen atoms in the methane molecule with chlorine, with the molecular formula CH2Cl2. It is a colorless, transparent, heavier than water, volatile liquid with an ether-like smell and sweetness. It does not burn, but forms an explosive mixture when mixed with high concentrations of oxygen. Dichloromethane is slightly soluble in water, miscible with most commonly used organic solvents, and can also be miscible with other chlorinated solvents, ether, ethanol and N, N-dimethylformamide in any proportion. Dichloromethane is difficult to dissolve in liquid ammonia at room temperature, but can quickly dissolve in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, and ethyl acetoacetate. Relative density 1.3266 (20/4°C). Melting point -95.1°C. Boiling point 40°C. Non-flammable low-boiling point solvent, often used to replace flammable petroleum ether, ether, etc., and can be used as a dental local anesthetic, refrigerant and fire extinguishing agent, etc.

Product Application of Dichloromethane CAS#75-09-2

Solvent is the main use of dichloromethane. Dichloromethane has strong solubility, low boiling point, relatively low toxicity and relatively good reaction inertness, making it the most frequently used organic solvent in organic synthesis. As a solvent, its status is almost equivalent to water in inorganic salt chemistry. A large amount of it is used in the manufacture of safe film and polycarbonate, and the rest is used as coating solvent, metal degreasing agent, aerosol spray, polyurethane foaming agent, release agent, paint stripping agent.
