Abstract
Process for obtaining alkenyl esters of carboxylic acids in the gas phase by reacting a carboxylic acid with one of olofin and with oxygen to oxygenated gases, at elevated temperature, possibly under elevated pressure, using a support catalyst containing palladium carboxylate and, evantually, of activators, characterized in that in the initial period of the process, at a temperature of between 100 and 250ºC, the concentration of the carboxylic acid in the gas entering the reactor rises continuously or in stages until reaching the final concentration, the ratio between the initial concentration of cartoxylic acid and the final concentration at 0.1 to 0.8, and the final concentration being reached after 1 to 60 hours.
