Abstract
A continuous process for the manufacture of methyl chloride, characterized by: (1) reacting methanol and hydrogen chloride, which optionally can be part of the unreacted mixed effluent from the partial reaction of methanol and hydrochloric acid in an aqueous solution of zinc chloride, in a reactor under reflux conditions and in the absence of zinc chloride catalyst, and, optionally, removing part of the excess water of reaction. (2) separating a gaseous stream from heads; (3) condense the gaseous stream of heads and feed back to the upper portion of the reactor a mixture of azeotrope of hcl-h2o, water and methanol.
