  • PROCESS AND APPARATUS FOR VAPOR PHASE PURIFICATION DURING HYDROCHLORINATION OF MULTI-HYDROXYLATED ALIPHATIC HYDROCARBON COMPOUNDS
    Publication number: 20110152580
    Abstract: A process for converting multihydroxylated-aliphatic hydrocarbon compound(s) and/or ester(s) thereof to chlorohydrins and/or esters thereof is disclosed in which one or more of multihydroxylated-aliphatic hydrocarbon compound(s) and/or ester(s) thereof and/or monochlorohydrin(s) and/or ester(s) thereof with at least one chlorinating feed stream comprising at least one chlorinating agent and at least one impurity having a boiling point below the boiling point of the chlorohydrin product having the lowest boiling under hydrochlorination conditions, optionally in the presence of water, one or more catalyst(s), and/or one or more heavy byproduct(s) in a reaction vessel under hydrochlorination conditions, wherein the liquid-phase reaction mixture is maintained at a temperature below the boiling point of the chlorohydrin product having the lowest boiling point under hydrochlorination conditions and greater than the boiling point(s) of the at least one impurity and a vapor phase vent stream comprising the at least o
