Methylene chloride / MC is Colorless liquid,with characteristic odor.Relative density D4 201.326, melting point-96.7℃, Boiling point: 40.4℃, If it is mixed with high concentrated Oxygen, the explosive mixture is formed but it is not inflammable. It is one of the low-boiling-Point industrial solvents that have small ltoxicity, no inflammable.It has good solubility for many resin, waxand fat, soluble in water slightly, easy soluble in other chloro solvent, ethoxyethane and ethanol. Dichloromethane can take place hydrolysis with water in a certain temperature. The commercial dichloromethane often contains stabilizer in order to prevent decomposition.
