How flammable is dichloromethane?
Dichloromethane, commonly called methylene chloride, is a solvent that is widely used in chemical research and manufacturing. It is a highly volatile liquid (see fast facts table), but it is neither flammable nor explosive in air.
Is dichloromethane corrosive to metals?
Conditions to Avoid: Excess heat, attacks some plastics, rubber, and coatings, confined spaces, When no water is present, dichloromethane is not corrosive to metals.
How reactive is dichloromethane?
Reactivity Profile Dichloromethane reacts vigorously with active metals such as lithium, sodium and potassium, and with strong bases such as potassium tert-butoxide. Dichloromethane is incompatible with strong oxidizers, strong caustics and chemically active metals such as aluminum or magnesium powders.
What makes dichloromethane a good solvent?
While dichloromethane isn’t miscible with water, it is able to dissolve a wide range of organic compounds. These properties, combined with its volatility, makes DCM a highly effective solvent in many industrial processes. Most commonly, DCM is used as a paint remover.

Is dichloromethane a neurotoxic?
It is widely used as an industrial solvent. In considering its neurotoxicity the CNS-depressant effects of both narcotic and hypoxic action must be taken into account, hypoxia being induced by the established biotransformation of DCM to carbon monoxide (CO).
What functional group is dichloromethane?
(i) The functional group in CH2Cl2 is chlorine. (ii) CH2Cl2 has one carbon atom and has to be named as the derivative of methane. (iii) CH2Cl2 contains 2 chlorine atoms, therefore the prefix dichloro- is to be added to the parent alkane, methane. (iv)Therefore, IUPAC name is dichloromethane.
Why is dichloromethane not miscible in water?
Organic solvents like dichloromethane are immiscible in water because water is, by contrast, a very polar solvent. Organic solvents, like ethyl acetate, are mostly less dense than water.
