Abstract

The paper presents an investigation of the deuterodesulfurization (DDS) of thiophene and 2,5 dihydrothiophene using nuclear magnetic resonance and mass spectral analysis. The results indicate that a mechanism for thiophene hydrodesulfurization (HDS) over PbMo6S8 must account for a maximum of 3.2 deuterium atoms being incorporated into 1,3-butadiene. Other mechanisms which predict fewer than 3.2 deuteriums in each 1,3-butadiene molecule are consistent with the results of this study, assuming that there is an exchange step which increases the overall deuterium content and yield the observed distribution of deuterated butadiene.
