Title (EN) PROCESS FOR OPTIMIZING THE PRODUCTION OF KETONES OR ALDEHYDES
(FR) PROCÉDÉ D'OPTIMISATION DE PRODUCTION DE CÉTONES OU ALDEHYDES
Abstract: front page image
(EN)The process according to the invention targets the optimization of the production of ketones or of aldehydes obtained by condensation followed by dehydration and hydrogenation of the ketones or aldehydes in a reactor (3), by carrying out a membrane pervaporation step (6) that makes it possible to partially dehydrate a fraction (5) exiting the reactor and to recycle the dehydrated concentrate (7) to said reactor (3).
(FR)Le procédé selon l'invention vise à l'optimisation de la production de cétones ou d'aldéhydes obtenus par la condensation suivie de la déshydratation et hydrogénation des cétones ou aldéhydes dans un réacteur (3), en effectuant une étape de pervaporation membranaire (6) permettant de déshydrater partiellement une fraction sortante du réacteur (5) et de recycler le concentré déshydraté (7) dans ledit réacteur (3).
