ABSTRACT:
A process for the production of cycloalkane epoxides from cycloalkenes in the presence of an oxide catalyst, oxygen and a carboxylate ion source via air oxidation is described. The oxide catalyst may have as a cation boron, chromium, iron, nickel, copper, zinc or terbium or mixtures thereof. Combination catalysts such as ferric oxide/zinc oxide and nickel oxide/copper oxide/chromium oxide/boric oxide complexes are also found to be useful. 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.
