ABSTRACT:
A method for preparing supported palladium-gold catalysts is disclosed. The method comprises increasing the porosity of a titanium dioxide support, impregnating the support with a palladium salt, a gold salt, and an optional alkali metal or ammonium compound, and reducing the calcined support. The resultant supported palladium-gold catalysts have increased activity in the acetoxylation.
