Abstract: A process is described for the removal of dimethyl ether in methyl chloride by catalytic cleavage by means of hydrogen chloride. Dimethyl ether is present as an impurity in crude methyl chloride produced by the catalytic esterification of methanol. The crude methyl chloride is cooled so that water and hydrogen chloride separate out. Gaseous hydrogen chloride is then added to the methyl chloride in an amount corresponding to at least twice the molar amount of dimethyl ether, and the gaseous mixture is passed over a methanol esterification contact catalyst at an elevated temperature.

Abstract: of the disclosure: Many halogenated hydrocarbons, such as methylene chloride or fluorotrichloromethene, are slowly hydrolyzed even in the presence of small amounts of water. It has been found that they can be stabilized by adding thereto from 0,001 to 10 % by weight of a tertiary amine of the formula RR1R2N wherein R and R1, independent from each other, represent alkyl groups with from 1 to 10 carbon atoms and R2 represents an isopropyl, butyl (2), tertiary butyl or cyclohexyl group.
