Abstract
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° C., and a pressure of the reaction is 1013 to 3039 hPa (absolute pressure).
