Methylene chloride is a kind of organic matter, the molecular formula is CH2Cl2, a colorless transparent liquid, with a pungent odor similar to ether, slightly soluble in water, soluble in ethanol and ether. Under normal conditions, it is a non-flammable solvent with low boiling point. When its vapor becomes a high concentration in high temperature air, it will generate weakly burning mixed gas [8] , commonly used in place of flammable petroleum ether ether, etc.
