bbhydrosulfurization of Ethanethiol over Alumina

Abstract

In the dehydrosulfurization of ethanethiol over alumina catalyst, diethyl sulfide were predominantly formed at lower reaction temperature, and ethylene was the main product at higher temperature.
Diethyl sulfide was also formed at lower temperature in the thermal desorption of ethanethiol adsorbed on alumina. Infrared absorption spectra of ethanethiol adsorbed over alumina indicated that the -SH group of the ethanethiol was dissociated and that the interaction with the catalyst surface produced the hydrogen bonding hydroxyl group.
The adsorption scheme of ethanethiol in the dehydrosulfurization was proposed.
