Definitions

  • EP 1 752 435 Al discloses another process for producing a chlorohydrin by reaction between a multihydroxylated aliphatic hydrocarbon and/or an ester thereof and aqueous hydrogen chloride to produce chlorohydrins, esters of chlorohydrins, or mixtures thereof under atmospheric condition in which a purge from the reactor bottom is fed to a stripper in which partial stripping of most of unreacted hydrogen chloride, the water from the aqueous hydrogen chloride reactant and water that is formed during the course of the reaction (also referred to herein as "water of reaction"), from the reaction mixture is carried out and a distillation or stripping column is fed with the liquid phase from the stripper.
  • One embodiment of the catalyst that may be present is generally represented by Formula (a) shown below wherein the functional group "R'” includes a functional group comprising an amine, an alcohol, a halogen, a sulfhydryl, an ether; or an alkyl, an aryl or alkaryl group of from 1 to about 20 carbon atoms containing said functional group; or a combination thereof; and wherein the functional group "R” may include a hydrogen, an alkali, an alkali earth or a transition metal or a hydrocarbon functional group.
  • the functional group "R'” includes a functional group comprising an amine, an alcohol, a halogen, a sulfhydryl, an ether; or an alkyl, an aryl or alkaryl group of from 1 to about 20 carbon atoms containing said functional group; or a combination thereof; and wherein the functional group "R” may include a hydrogen, an alkali, an alkali earth or a transition metal or a hydrocarbon functional group
  • step (b) that is greater than the temperature required to maintain dissolution of the hydrogen chloride present in the mixture provided in step (a), and/or adjusting the rate at which a stripping agent such as steam is introduced to strip hydrogen chloride from the mixture (a).
  • the mixture provided in step (a) is passed through a pressure letdown step for degassing the mixture prior to distilling and/or fractionating the mixture.
  • the pressure letdown step and/or a surge vessel may also be used to help regulate the flow of the mixture into the distillation and/or fractionation step.
  • the at least one separation device (2) preferably comprises at least one flash vessel and the at least one reactor (1) is connected to at least one liquid- vapor contacting device of the at least one separation device (2) via the at least one flash vessel, whereby the feed stream conducted from the reactor (1) is separated into a vapor phase and a liquid phase in the flash vessel by reducing the pressure on the liquid phase and the separated liquid phase is introduced into the liquid-vapor contacting device of separation device (2) for distillation or fractionation.
