Dichloromethane CAS#75-09-2
Dichloromethane CAS#75-09-2 Excellent Solubility: Dichloromethane, also known as methylene chloride, features outstanding dissolving capacity for a wide range of organic substances. It is miscible with common organic solvents including ethanol, ether, acetone, benzene and carbon tetrachloride, and slightly soluble in water. Its superior solubility endows it with extensive applicability in industrial dissolution and extraction processes.
Stable Chemical Properties: The compound exhibits relatively high chemical stability at room temperature and normal pressure, resisting decomposition under conventional storage and usage conditions. It does not react with dilute acids and dilute alkalis readily, and maintains stable fundamental properties in conventional industrial application environments.
Versatile Industrial Applications: It is widely used as an efficient organic solvent, extraction agent and cleaning agent in chemical industry, pharmaceutical manufacturing, food processing and electronic industry. It is also commonly adopted for organic synthesis reaction medium and residue cleaning in precision equipment processing.
Volatile & Low-viscosity Nature: This product is a colorless, transparent, volatile liquid with low viscosity and a mild sweet odor. Its excellent volatility ensures no residual adhesion after application, which is suitable for scenarios requiring clean and rapid solvent volatilization.
Dichloromethane, with the molecular formula CH2Cl2, is a colorless transparent volatile liquid with a faint sweet odor. It is slightly soluble in water, with a water solubility of 13.2 g/L at 25°C, and infinitely miscible with ethanol, diethyl ether, acetone and most organic solvents. The substance has low viscosity and strong dissolving power for fats, resins, rubbers and various organic compounds. It is chemically stable under normal temperature, but may undergo slow hydrolysis in high-temperature humid environment. It possesses low flammability compared with other chlorinated alkanes and is widely applied in industrial production and laboratory research as a high-efficiency low-toxicity solvent and reaction auxiliary material.
