Abstract
The intermolecular protium-deuterium exchange occurring between isobut ane and D2O-exchanged acidic catalysts, such as sulfated zirconia and H-Beta zeolite, has been studied in the low temperature range: 20-200 degrees C. The induction period, which is apparent at 100 degrees C an d below, is suppressed when small amounts of isobutene are added to is obutane. The results are discussed with respect to the formation of al kene intermediates from alkanes at low temperature on an acidic cataly st.
