ABSTRACT:
A process for the production of cycloalkane epoxides from cycloalkenes in the presence of a tungsten or zirconium containing catalyst, oxygen and a carboxylate ion source via air oxidation is described. For example, cobalt tungstate, nickel tungstate, silver tungstate and manganese tungstate are useful catalysts. Active zirconates are cerium zirconate, cadmium zirconate and lead zirconate. The reaction is conducted at a temperature in the range of 50.degree. to 150.degree. C. and a pressure of one atmosphere or greater. Cycloalkane epoxides are useful in the preparation of resins, plasticizers, etc.
