Abstract
A process for the manufacture of a Pd/Au/alkali metal catalyst, preferably a fluid bed catalyst used in the production of vinyl acetate comprising impregnating a microspheroidal support with a hydroxy-free metal salt solution of Pd and Au substantially free of barium and halide, reducing said salts to deposit Pd and Au on said support surface and impregnating said support with a halide-free metal salt of an alkali metal (preferably potassium).
