Katalysator aktiviert durch ein Multimetaloxid

摘要

A catalyst comprising a promoted mixed metal oxide is useful for the vapor phase oxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated carboxylic acid and for the vapor phase ammoxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated nitrile. The multi-metal oxide catalyst comprises at least one element selected from the group consisting of Ni, Pd, Cu, Ag and Au.
