The present invention relates to a process for the separation of vinyl acetate from a gas mixture formed in the gas phase in the conversion of ethylene with acetic acid and oxygen over palladium or palladium containing catalysts, wherein part of the bottom product removed from the distillation column in which pure vinyl acetate is produced is heated by the water vapour-saturated CO2 stream which is obtained from the carbon dioxide desorber, and is fed back to the distillation column in which pure vinyl acetate is produced.

La présente invention concerne un procédé permettant de séparer de l'acétate de vinyle d'un mélange de gaz formé dans la phase gazeuse au cours de la conversion d'éthylène avec de l'acide acétique et de l'oxygène sur palladium ou sur des catalyseurs contenant du palladium. Une partie du produit éliminé au bas de la colonne de distillation dans laquelle l'acétate de vinyle pur est produit, est chauffée par le courant de vapeur d'eau et de CO2 saturé qui est obtenu du désorbeur de dioxyde de carbone, et est réintroduite dans la colonne de distillation dans laquelle l'acétate de vinyle pur est produit.
