Patent number: 8216964Abstract: The present invention addresses at least four different aspects relating to catalyst structure, methods of making those catalysts and methods of using those catalysts for making alkenyl alkanoates. Separately or together in combination, the various aspects of the invention are directed at improving the production of alkenyl alkanoates and VA in particular, including reduction of by-products and improved production efficiency. A first aspect of the present invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A second aspect pertains to a palladium/gold catalyst or pre-catalyst that is based on a layered support material where one layer of the support material is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or pre-catalyst on a zirconia containing support material.Type: GrantFiled: July 31, 2008Date of Patent: July 10, 2012Assignee: Celanese International Corp.Inventors: Tao Wang, Leslie Wade, Ioan Nicolau, Yumin Liu, Victor Wong, Barbara Kimmich, Jun Han, Valery Sokolovskii, Alfred Hagemeyer, David M.

Patent number: 7518014Abstract: The present invention relates to a method of producing a catalyst or pre-catalyst suitable for assisting in the production of alkenyl alkanoates. The method includes contacting a modifier precursor to a support material to form a modified support material. One or more catalytic component precursors (palladium or gold) may be contacted to the modified support material. The atomic ratio of gold to palladium is preferably in the range of about 0.3 to about 0.90. The support materials with the catalytic component may then be reduced using a reducing environment. A composition for catalyzing the production of an alkenyl alkanoates including a modified support material with palladium and gold is also included within the invention. Catalysts of the present invention may be used to produce alkenyl alkanoates in general and vinyl acetate in particular and are useful to produce low EA/VA ratios while maintaining or improving CO2 selectivity.Type: GrantFiled: November 21, 2005Date of Patent: April 14, 2009Assignee: Celanese International Corp.Inventors: Barbara Kimmich, Leslie E.
