Dichloromethane

Dichloromethane is a member of the methyl chloride category, and it is methane in which two hydrogens have been replaced by chlorine. It is a dense at room temperature (bp 40°C, d = 1.33), non-flammable colorless liquid with a sweet taste, permeability, and smell similar to ether.   andsoluble in ethanol and ether. As a non-flammable low-boiling solvent. It is often used to replace flammable petroleum ether and ether. It is not flammable when exposed to high temperatures, but may release toxic chloride fumes. Its vapor is a highly concentrated narcotic.  

Dichloromethane has the advantages of strong solubility and low toxicity. It is widely used in the manufacture of safety film and polycarbonate, and the rest is used as coating solvent, metal degreasing agent, aerosol spraying agent, polyurethane foaming agent, mold release agent, and release agent. Lacquer.
