Stability of dichloromethane

The molecular formula of dichloromethane: CH2Cl2. Colorless, transparent liquid, with a surprising odor like ether. Do not dissolve in water, soluble in ethanol and ether. Is not combustible low boiling point solvents, commonly used to replace flammable petroleum ether, ether and so on.

Two hydrogen atoms is  methane molecule which  a compound in are replaced by chlorine. Dichloromethane is colorless, transparent, watery, volatile liquid, and has a similar ether odor and sweetness, does not burn, but mixes with high concentrations of oxygen to form an explosive mixture. Dichloromethane dissolved in water, with the vast majority of commonly used organic solvents miscible, and other chlorine solvents, ether, ethanol can also be any proportion of miscible. Dichloromethane can be quickly dissolved in phenol, aldehydes, ketones, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, ethyl acetoacetate.

Pure dichloromethane without flash point, containing an equal volume of dichloromethane and gasoline, solvent naphtha or toluene solvent mixture is not flammable, but when the dichloromethane and acetone or methanol liquid in a 10: 1 ratio of mixing, The mixture has a flash point, the vapor and air to form an explosive mixture, the explosion limit of 6.2% to 15.0% (volume). Dichloromethane is the least toxic to methane chloride, and its toxicity is only 0.11% of the carbon tetrachloride toxicity. If the dichloromethane directly splashed into the eyes, there is pain and corrosion. The steam of methylene chloride has an anesthetic effect. When a serious risk of poisoning should be immediately out of contact and moved to fresh air, some symptoms of poisoning will be alleviated or disappeared, will not cause lasting damage
