  • Process for producing isopropyl chloride
    Patent number: 7078576
    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).

  • Less colored trans-1,3-dichloropropene and process for its production
    Patent number: 6881872
    Abstract: 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 C6 compounds, 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 C6 compounds as a high boiling component and to obtain trans-1,3-dichloropropene as a low boiling component.
