DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993.

Acetals are geminal-diether derivatives of aldehydes or ketones, formed by reaction with two equivalents (or an excess amount) of an alcohol and elimination of water. Ketone derivatives of this kind were once called ketals, but modern usage has dropped that term. It is important to note that a hemiacetal is formed as an ...
WebThe halogenation of alkenes is carried out in a neutral organic solvent such as carbon tetrachloride (CCl 4 or dichloromethane, DCM ( CH2Cl2) that cannot act as a nucleophile when the halonium ion is formed. On the other hand, if the reaction is carried out in water, for example, a halohydrin is formed by the addition of the water to the ...
