CATALYST SYSTEM FOR PRODUCING KETONES FROM EPOXIDES

摘要

PROBLEM TO BE SOLVED: To adapt the rearrangement of epoxides to ketones in such a way that the amount of catalyst or the reaction time can be reduced.SOLUTION: A catalyst composition contains at least one precious metal and at least one mixed oxide, wherein the mixed oxide contains zirconium dioxide and silicon dioxide, wherein the precious metal is supported and the support is not entirely made of the mixed oxide, and wherein a mass ratio of zirconium dioxide to silicon dioxide in the mixed oxide is 86:14 to 99.9:0.1.SELECTED DRAWING: None
