摘要

In situ solid-state NMR spectroscopy was employed to study the kinetics of hydrogen/deuterium exchange and scrambling as well as 13C scrambling reactions of labeled propane over Al2O3-promoted sulfated zirconia (SZA) catalyst under mild conditions (30-102° C). Three competitive pathways of isotope redistribution were observed during the course of the reaction:(1) a regioselective H/D exchange between acidic protons of the ...
