Title (EN) PROCESS FOR RECOVERING HALOGEN PROMOTERS AND REMOVING PERMANGANATE REDUCING COMPOUNDS
(FR) PROCÉDÉS DE RÉCUPÉRATION DE PROMOTEURS D'HALOGÈNE ET ÉLIMINATION DE COMPOSÉS RÉDUCTEURS À BASE DE PERMANGANATE
Abstract: front page image
(EN)This invention relates to processes for producing acetic acid and, in particular, to improved processes for recovering C2+ alkyl halides and removing permanganate reducing compounds formed during the carbonylation of methanol in the presence of a Group VIII metal carbonylation catalyst to produce acetic acid.
(FR)La présente invention concerne des procédés de production d'acide acétique et, en particulier, des procédés améliorés permettant de récupérer des halogénures d'alkyle en C2+ et d'éliminer les composés réducteurs à base de permanganate formés lors de la carbonylation du méthanol en présence d'un catalyseur de carbonylation contenant un métal du groupe VIII pour produire de l'acide acétique.
