Chemical Properties: 

Methylene chloride reacts strongly with active metals such as potassium, sodium, and lithium, and strong bases, for instance, potassium tert-butoxide. However, the compound is incompatible with strong caustics, strong oxidizers, and metals that are chemically active such as magnesium and aluminum powders.
It is noteworthy that methylene chloride can attack some forms of coatings, plastic, and rubber. In addition, dichloromethane reacts with liquid oxygen, sodium-potassium alloy, and nitrogen tetroxide. When the compound comes into contact with water, it corrodes some stainless steels, nickel, copper as well as iron.
When exposed to heat or water, dichloromethane becomes very sensitive as it is subjected to hydrolysis that is hastened by light. Under normal conditions, solutions of DCM such as acetone or ethanol should be stable for 24 hours.
Methylene chloride does not react with alkali metals, zinc, amines, magnesium, as well as alloys of zinc and aluminum. When mixed with nitric acid or dinitrogen pentoxide, the compound can vigorously explode. Methylene chloride is flammable when mixed with methanol vapor in the air.
Since the compound can explode, it is important to avoid certain conditions such as sparks, hot surfaces, open flames, heat, static discharge, and other ignition sources.
