Produktdetaljer

Dichloromethane, en organisk forbindelse, is a colorless transparent liquid with a pungent odor similar to that of ether. Slightly soluble in water, soluble in ethanol and ether, under the usual conditions of use is a non-combustible low boiling point solvent, its vapor in high temperature air becomes a high concentration, it will generate a weak burning mixture of gases, commonly used to replace flammable petroleum ether, ether and so on.
