Process for hydrochlorination of multihydroxylated aliphatic hydrocarbons

摘要

A process for producing a chlorohydrin, an ester of a chlorohydrin, or a mixture thereof including the steps of contacting, in a hydrochlorination reactor, a multihydroxylated aliphatic hydrocarbon, an ester of a multihydroxylated aliphatic hydrocarbon, or a mixture thereof with a source of a hydrogen chloride, in the presence of a hydrophobic or extractable carboxylic acid catalyst is provided.

1. A process for producing a chlorohydrin, an ester of a chlorohydrin, or a mixture thereof comprising the steps of:
(a) contacting, in a hydrochlorination reactor, a multihydroxylated aliphatic hydrocarbon, a multihydroxylated aliphatic hydrocarbon ester, or a mixture thereof with a source of hydrogen chloride, in the presence of a hydrophobic carboxylic acid catalyst to produce a first product stream comprising chlorohydrins, hydrophobic chlorohydrin esters, or a mixture thereof; (b) phase separating the first product stream into a non-polar hydrophobic liquid stream and a polar non-hydrophobic liquid stream, wherein the polar non-hydrophobic liquid stream comprises water and hydrogen chloride and wherein the non-polar hydrophobic liquid stream comprises the non-polar hydrophobic chlorohydrin esters, and the non-polar hydrophobic carboxylic acid catalyst; and (c) decanting the non-polar hydrophobic liquid stream from the polar non-hydrophobic liquid stream after the phase separating step (b).
