Products Description of Dichloromethane CAS#75-09-2
Dichloromethane is a compound formed by replacing two hydrogen atoms in the methane molecule with chlorine, with the molecular formula CH2Cl2. It is a colorless, transparent, heavier than water, volatile liquid with an ether-like odor and sweetness. It does not burn, but forms an explosive mixture when mixed with high concentrations of oxygen. Dichloromethane is slightly soluble in water and miscible with most commonly used organic solvents. It can also be miscible with other chlorinated solvents, ether, ethanol and N, N-dimethylformamide in any proportion.
