Title (EN) CONVERSION OF A MULTIHYDROXYLATED-ALIPHATIC HYDROCARBON OR ESTER THEREOF TO A CHLOROHYDRIN
(FR) CONVERSION D'UN HYDROCARBURE ALIPHATIQUE MULTIHYDROXYLE OU L'UN DE SES ESTERS EN CHLOROHYDRINE
Abstract:
(EN) The present invention relates to a process for converting a multihydroxylated-aliphatic hydrocarbon or ester thereof to a chlorohydrin, by contacting the multihydroxylated-aliphatic hydrocarbon or ester thereof starting material with a source of a superatmospheric partial pressure of hydrogen chloride for a sufficient time and at a sufficient temperature, and wherein such contracting step is carried out without substantial removal of water, to produce the desired chlorohydrin product; wherein the desired product or products can be made in high yield without substantial formation of undesired overchlorinated byproducts. In addition, certain catalysts of the present invention may be used in the present process at superatmospheric, atmospheric and subatmospheric pressure conditions with improved results.
(FR) L'invention porte sur un processus de conversion d'un hydrocarbure aliphatique multihydroxylé ou l'un de ses esters en chlorohydrine, en mettant l'hydrocarbure ou son ester de départ en contact avec du chlorure d'hydrogène à pression partielle super-atmosphérique pendant un temps suffisant à une température suffisante, et sans pratiquement d'extraction d'eau. On obtient ainsi le ou les produits de chlorohydrine désirés avec un fort rendement et sans la formation de dérivés surchlorés indésirables. De plus, certains des catalyseurs de l'invention peuvent s'utiliser dans ledit processus à des pressions super-atmosphérique, atmosphérique et sub-atmosphérique avec de meilleurs résultats.
