Physical and chemical properties of tran***rent colorless volatile liquid. With a pungent odor similar to ether. About 50 times more soluble in water, soluble phenols, aldehydes, ketones, acetic acid, phosphate, ethyl acetoacetate, cyclohexylamine. And other chlorinated hydrocarbon solvents ethanol, ethyl ether and N, N-dimethylformamide immiscibility. The relative density of 1.3266 (20 / 4 ℃). Melting point -95.1 ℃. Boiling point of 40 ℃. Ignition point 640 ℃. Viscosity (20 ℃) &©|8203;&©|8203;0.43*** ¡¤ s. Refractive index nD (20 ℃) &©|8203;&©|8203;1.4244. Critical temperature 237 ℃, critical pressure 6.0795***. After pyrolysis produces a small amount of HCl and phosgene, and long-term water heating, to generate formaldehyde and HCl. Further chlorination can CHCl3 and CCl4. Colorless, volatile liquid. Melting point -95.1 ℃, boiling point 40 ℃, relative density 1.3266 (20 / 4 ℃). Slightly soluble in water, soluble in ethanol, ether and so on. Difficult to burn. Vapors form explosive mixtures with air, explosive limits 6.2% to 15.0% (volume). Methylene chloride reacts with sodium hydroxide formaldehyde. Industry, methylene chloride and chlorine gas by the reaction, pure product obtained after distillation, is an excellent organic solvent, often used to replace flammable petroleum ether, ethyl ether, refrigerants and fire extinguishing agent |
