ULTRAHIGH EFFICIENCY ALKYLENE OXIDE CATALYSTS HAVING ENHANCED STABILITY

摘要

Catalysts for the production of alkylene oxide by the epoxidation of alkene with oxygen in the presence of an efficiency enhancing gaseous member of a redox-half reaction pair comprise a silver impregnated support containing an efficiency enhancing amount of at least one efficiency-enhancing salt of a member of a redox-half reaction pair and a sufficient amount of stability-enhancing component to provide enhanced catalytic stability as compared to a similar catalyst which does not contain such stability-enhancing component.
