Title
(EN) METHOD FOR INTEGRATING AMMOXIMATION REACTION AND SEPARATION AND DEVICE THEREOF

Abstract
(EN) A method and device for integrating an ammoximation reaction and separation. In the method, titanium-silicon molecular sieve is used as a catalyst; an ammoximation reaction of a ketone, hydrogen peroxide and ammonia is carried out to generate an oxime; after separating a clear liquid from the reaction material by passing through cross-flow filtration, an inert alkane solvent is added to an extracted portion to extract the oxime; and the turbid liquid containing the catalyst is recycled back into the reaction system. The method for integrating reaction and separation can reduce the filtration load of a cross-flow membrane, reducing catalyst consumption, reducing investment and operation costs, and having excellent industrial application prospects.
(FR) L’invention concerne un procédé et un dispositif d’intégration d’une réaction d’ammoximation et d’une séparation. Dans le procédé, un tamis moléculaire au titane-silicium est utilisé en tant que catalyseur ; une réaction d’ammoximation d’une cétone, de peroxyde d’hydrogène et d’ammoniac est mise en œuvre pour produire une oxime ; après séparation d’un liquide limpide du matériau réactionnel par filtration à courants croisés, un solvant alcane inerte à une partie extrudée pour extraire l’oxime est ajouté ; et le liquide trouble contenant le catalyseur dans le système réactionnel est recyclé. Le procédé d’intégration d’une réaction et d’une séparation peut réduire la charge de filtration d’une membrane à courants croisés, en réduisant la consommation de catalyseur, en réduisant les frais d’investissement et d’exploitation, avec d’excellentes perspectives d’applications industrielles.
