The invention describes an integrated process for the production of vinyl acetate which comprises te steps of: (a) contacting in a first reaction zone a gaseous feedstock comprising essentially ethane with a molecular oxygen- containing gas in the presence of a catalyst to produce a first product stream comprising acetic acid and ethylene; (b) contacting in a second reaction zone the first gaseous product stream with a molecular oxygen-containing gas in the presence of a catalyst to produce a second product stream comprising vinyl acetate; (c) separating the product stream from step (b) and recovering vinyl acetate from the product stream from step (b).

L'invention concerne un processus intégré de production d'acétate de vinyle consistant à (a) mettre en contact dans une première zone de réaction une charge gazeuse renfermant essentiellement de l'éthane avec un gaz contenant de l'oxygène moléculaire en présence d'un catalyseur de manière à produire un premier débit diluat contenant de l'acide acétique et de l'éthylène, (b) mettre en contact dans une seconde zone de réaction le premier débit diluat gazeux avec un gaz contenant de l'oxygène moléculaire en présence d'un catalyseur afin de produire un second débit diluat contenant de l'acétate de vinyle, (c) séparer le débit diluat de l'étape (b) et récupérer l'acétate de vinyle du débit diluat de l'étape (b).
