Abstract
A process for preparation of an alkyl halide, RX, from reaction between the corresponding alcohol, ROH, and a hydrogen halide, HX, which improves conversion of the hydrogen halide to the alkyl halide in a single pass through a reactor. The process comprises (A) contacting and reacting the hydrogen halide with a stoichiometric excess of the alcohol in a plug-flow reactor in which flow of a mixture comprising unreacted alcohol, unreacted hydrogen halide, the alkyl halide, and water is co-current; and (B) isolating and separating the alkyl halide.
