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&#xb0; C., and a pressure of the reaction is 1013 to 3039 hPa (absolute pressure).

Process for producing isopropyl chloride

Less colored trans-1,3-dichloropropene and a process for producing it, are presented. A composition comprising cis-1,3-dichloropropene, trans-1,3-dichloropropene and Ccompounds, is subjected to a distillation step and to a step of reacting chlorine or bromine, to remove cis-1,3-dichloropropene as a low boiling component, and then the residue is distilled to remove the chlorinated Ccompounds as a high boiling component and to obtain trans-1,3-dichloropropene as a low boiling component.
