    摘要: The present invention relates to a process for converting at least one multihydroxylated-aliphatic hydrocarbon and/or an ester thereof to at least one chlorohydrin and/or an ester thereof, comprising at least one reaction step in which the multihydroxylated-aliphatic hydrocarbon and/or ester thereof is contacted with hydrogen chloride under reaction conditions to produce the chlorohydrin and/or ester thereof, followed by at least one downstream processing step in which the effluents of the reaction step are processed, wherein the downstream processing step is performed in such conditions that the effluents containing the chlorohydrin and/or ester thereof are kept at a temperature of less than 12O° C. The invention allows to minimize the liberation of hydrogen chloride from the products of the hydrochlorination reaction, hence reducing the corrosion of the downstream equipment and reducing M the need to use costly corrosion resistant materials.

    摘要: A process and apparatus are disclosed for the purification of epichlorohydrin. The process includes distilling and/or fractionating a feed stream containing epichlorohydrin, dichlorohydrin(s), and one or more other substances, subjecting at least a portion of the liquid phase effluent to a dichlorohydrin dehydrochlorination process for converting residual dichlorohydrin(s) in the liquid phase effluent to epichlorohydrin, and recovering purified epichlorohydrin from the vapor phase effluent in which the distillation/fractionation pressure and/or temperature of step (1) is adjusted to retain at least 5 weight-percent epichlorohydrin in the liquid phase effluent. The apparatus for making purified epichlorohydrin includes a dehydrochlorination apparatus, a first liquid-vapor contacting apparatus, and a second liquid-vapor contacting apparatus connected to the dehydrochlorination apparatus for recycling a distillate to the dehydrochlorination apparatus. Advantages include more efficient recovery of epichlorohydrins and reduced capital investment in recovery equipment.
