Abstract

Dans un procédé de préparation du diacétoxybutène par réaction du butadiène, de l'acide acétique et de l'oxygène, le gaz d'évacuation sortant du système réactionnel ou du système de purificadon, contenant du butadiène et/ou de l'acide acétique, est mis en contact avec du diacétoxybutène et/ou du diacétoxybutane comme absorbant pour absorber le butadiène et/ou l'acide acétique. On peut utiliser comme absorbant une partie du diacétoxybutène séparé de la solution des produits de la réaction dans une tour de distillation. Dans ce cas, le butadiène et/ou l'acide acétique peuvent être recueillis en envoyant la solution d'absorption dans cette tour de distillation. On peut égalements utiliser comme absorbant du diacétoxybutane obtenu par hydrogénation directe du diacétoxybutène.
