Title
(EN) METHOD FOR PREPARING MERCAPTANS BY SULFHYDROLYSIS OF SULFIDES
(FR) PROCEDE DE PREPARATION DE MERCAPTANS PAR SULFHYDROLYSE DE SULFURES
Abstract
(EN)
The present invention concerns a method for sulfhydrolysis from dialkyl sulfides and hydrogen sulfide, in the presence of a specific catalyst based on titanium dioxide and/or zirconium dioxide, as well as the corresponding use of such a catalyst. The present invention also concerns a method for preparing mercaptans, in particular methyl mercaptan, from at least one alcohol and hydrogen sulfide, comprising said sulfhydrolysis method.
(FR)
La présente invention concerne un procédé de sulfhydrolyse à partir de dialkylsulfures et d'hydrogène sulfuré, en présence d'un catalyseur spécifique à base de dioxyde de titane et/ou de dioxyde de zirconium, ainsi que l'utilisation correspondante d'un tel catalyseur. La présente invention concerne également un procédé de préparation de mercaptans, en particulier de méthylmercaptan, à partir d'au moins un alcool et d'hydrogène sulfuré comprenant ledit procédé de sulfhydrolyse.
