Description:

Dichloromethane / Methylene Chloride is a colorless, transparent, and volatile liquid that is heavier than water. It has an ethereal smell and sweet taste. It does not burn. But it forms an explosive mixture when mixed with high concentrations of oxygen. Dichloromethane is slightly soluble in water. It is miscible with the most common organic solvents. It can be miscible with other chlorine-containing solvents, ether, ethanol and N,N-dimethylformamide in any ratio.
