The present invention is an industrially advantageous process for
isopropyl chloride production in which the catalytic activity can be
maintained under the milder reaction conditions than in the conventional
processes, and which requires no special reactor.Propylene and hydrogen
chloride is reacted in a gas phase, in the presence of iron or a
halogenated aluminum oxide (preferably, aluminum oxide reacted with
hydrogen chloride). Preferably, a temperature during the reaction is 20
to 100.degree. C., and a pressure of the reaction is 1013 to 3039 hPa
(absolute pressure).
