Abstract
It has now been found that a particularly active supported catalyst useful for the production of vinyl esters from ethylene, lower carboxylic acids with 2-4 carbon atoms, and oxygen in the gas phase at elevated temperature and at normal or elevated pressure can be obtained by any of the prior art methods of manufacturing the catalyst using three or four metals instead of the prior art recognized two metals or the newly described catalyst containing copper as a third metal U. S. 5,347,046 describes a catalyst containing the third metal copper. The metals which comprise the useful catalyst of this invention are palladium, gold, and at least one of rhenium or zirconium. The concentration of palladium on the support is from about 2 to about 14 grams/liter; the concentration of gold on the catalyst support is from about 1 to about 8 grams/liter, and, when used, the concentration of zirconium on the catalyst support is from about 0.5 to about 4 grams/liter and/or the concentration of rhenium on the catalyst support is from about 1 to about 8 grams/liter.
