INORGANIC OXIDE EXTRUDATES

摘要

AN EXTRUDATE COMPRISING AN INORGANIC OXIDE AND A COMB-BRANCHED POLYMER IS DISCLOSED. THE CALCINED EXTRUDATES ARE USEFUL CATALYSTS OR CATALYST SUPPORTS. A PALLADIUM-GOLD CATALYST PREPARED WITH A CALCINED TITANIA EXTRUDATE OF THE INVENTION IS USEFUL IN MAKING VINYL ACETATE FROM ETHYLENE, ACETIC ACID, AND OXYGEN OR OXYGEN-CONTAINING GAS. A CALCINED TRANSITION METAL ZEOLITE EXTRUDATE OF THE INVENTION IS USED AS A CATALYST IN OXIDIZING ORGANIC COMPOUNDS WITH HYDROGEN PEROXIDE. INCORPORATION OF A COMB-BRANCHED POLYMER IMPROVES THE MECHANICAL PROPERTIES OF INORGANIC OXIDE EXTRUDATES.
