Olefin reactivity for synthetic mordenites varies in the series ethylene, propylene, isobutylene. S study of the hydration of these alkenes on high-silicon zeolite ZHM displayed an unusual reactivity order: ethylen = propylene is greater than isobutylene oligomers zation of the catalyst and the formation of isobutylene oligomers increased at higher temperature; the yield of tert-butyl alcohol did not increase. These results may be explained by a molecular sieve effect for olefin hydration and not by sample deactivation and side reactions since even a partially carbonized catalyst did not display reduced activity in olefin hydration.
