Abstract
The present invention relates to improvements in known gold containing catalysts. In particular, the present invention relates to improving the stability and/or inhibition of deactivation of gold containing catalysts via the addition of an inorganic oxide, hydroxide, oxo-salt or oxo-acid. There is also disclosed a method for preparing said catalyst most suitably via an impregnation method. Such catalysts are useful in the production of vinyl chloride monomer.
