Abstract

Transformations of ethyloxirane, vinyloxirane and their mixture were studied over HZSM-5 and CuZSM-5 zeolites in the presence of hydrogen at 363 K. Ethyloxirane underwent single ring-opening and deoxygenation, while ring expansion was the main transformation pathway for vinyloxirane. Reactions of the mixture revealed that the active sites for adsorbed oxygen mediated ring transformations can be separated on HZSM-5 from those, where the adsorption of the vinyl group and the ring oxygen is a requirement. This cannot be done on CuZSM-5.
