Dichloromethane Alias: Methylene chloride; Methylene dichloride; Chloromethylene chloride; Methylene bichloride English Name: Dichloromethane Abbreviation: DCM Chemical Formula: CH₂Cl₂ Molecular Weight: 84.93 CAS Registry Number: 75-09-2 EINECS Number: 200-838-9 Melting Point: -97 °C Boiling Point: 39.75 °C Density: 1.325 g/mL Flash Point: 30 °C Appearance: Colorless, transparent, volatile liquid with an ether-like odor and sweet taste. Water Solubility: Insoluble in water Uses: 1. Dichloromethane is widely used for its strong solvent properties, particularly in the production of safety film and polycarbonate. It is also used as a solvent in coatings, metal degreasing, aerosol propellants, polyurethane foaming agents, mold release agents, and paint strippers. 2. As a colorless liquid, it serves as a reaction medium in the pharmaceutical industry. It is also employed as a solvent in film production, petroleum dewaxing, aerosol propellants, organic synthesis extraction, and as a foaming agent in the production of polyurethane and other foam plastics, as well as a metal cleaning agent. 3. In China, dichloromethane is primarily used in film production and the pharmaceutical sector. 4. It is used for grain fumigation and as a refrigerant in low-pressure refrigeration and air conditioning systems. In the production of polyether-type urethane foam, it acts as an auxiliary foaming agent, and as a foaming agent in the extrusion of polysulfone-type foam plastics.
