Title (EN) PROCESS FOR PRODUCING DIACETOXYBUTENE
(FR) PROCEDE DE PRODUCTION DE DIACETOXYBUTENE
Abstract: front page image
(EN)A process for producing diacetoxybutene which comprises supplying butadiene, acetic acid, and oxygen to a reaction zone where a solid catalyst containing palladium is present, wherein the oxygen is supplied in the form of fine bubbles of a gas containing at least 7 mol% oxygen. Thus, the butadiene can be efficiently reacted and diacetoxybutene can be produced in high yield.
(FR)L'invention concerne un procédé de production de diacétoxybutène, consistant à fournir du butadiène, de l'acide acétique et de l'oxygène dans une zone de réaction dans laquelle se trouve un catalyseur solide contenant du palladium, l'oxygène étant fourni sous la forme de fines bulles d'un gaz contenant au moins 7 moles % d'oxygène, de façon à faire réagir efficacement le butadiène et à produire du diacétoxybutène avec un rendement élevé.
