Abstract
Official abstract text for this publication.
The present invention relates to a process for the separation of vinyl acetate from a gas mixture formed by the reaction of ethylene with acetic acid and oxygen in the gas phase over catalysts comprising palladium or palladium compounds.
First claim
Opening claim text (preview).
We claim: 1. A process for the separation of vinyl acetate from a gas mixture formed by the reaction of ethylene with acetic acid and oxygen in the gas phase over catalysts comprising palladium or palladium compounds comprising: a) introducing said gas mixture leaving a vinyl acetate reactor into a predewatering column, b) cooling a gas mixture leaving the top of the predewatering column below 85° C. in a countercurrent heat exchanger, c) further cooling a gas mixture or a gas…
