HOE 79/F 289 PROCESS FOR SEPARATING WATER FROM MIXTURES THEREOF WITH VINYL ACETATE AND ACETIC ACID Abstract of the disclosure: Process for separating water from a gas mixture, obtained in the manufacture of vinyl acetate by reacting ethylene with acetic acid and oxygen in contact with catalysts containing palladium or palladium compounds in the gaseous phase and consisting essentially of acetic acid, vinyl acetate, water, carbon dioxide and ethylene, wherein a) the gas mixture leaving the reaction zone is condensed to give a condensate containing the main amount of acetic acid, of vinyl acetate and of water and b) an acetic acid solution containing the residual amount of vinyl acetate and water is prepared by ab- sorption of the non condensed gas in acetic acid, is characterized in that c) the condensate obtained in step a) and the solution obtained in step b) are introduced separately from each other into the same distillation column, the feeding point of the condensate being above the feeding point of the solution, the water is distilled off at the head of said column as azeotrope together with the vinyl acetate and d) the water phase is removed from the distillate separating into a water phase and a vinyl acetate phase.
