Title (EN) PROCESS FOR THE MANUFACTURE OF 6,10,14-TRIMETHYLPENTADECAN-2-ONE
(FR) PROCÉDÉ DE PRODUCTION DU 6,10,14-TRIMÉTHYLPENTADÉCAN-2-ONE
Abstract:
(EN) The present invention is directed to a process for the manufacture of 6,10, 14- trimethylpentadecan-2-one ("C18-ketone") comprising the step of hydrogenating a mixture of (5E,9E)-farnesylacetone and (5Z,9E)- farnesylacetone with hydrogen in the presence of a catalyst, whereby the catalyst is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds. Preferably the catalyst comprises a metal selected from the group consisting of palladium, platinum, rhodium, iridium and nickel and mixtures thereof.
(FR) L'invention concerne un procédé de production du 6,10,14-triméthylpentadécan-2-one ("cétone en C18") comprenant l'étape consistant à hydrogéner un mélange de (5E,9E)-farnésylacétone et de (5Z,9E)-farnésylacétone avec de l'hydrogène en présence d'un catalyseur, le catalyseur pouvant hydrogéner de préférence les liaisons doubles carbone-carbone par rapport aux liaisons doubles carbone-oxygène. Le catalyseur comprend de préférence un métal choisi dans le groupe constitué par le palladium, le platine, le rhodium, l'iridium et le nickel, et des mélanges de ceux-ci.
