Abstract
A study of the synthesis of thiophene from the reaction of butanol and CS2 over potassium-promoted Cr2O3/gamma-Al2O3 has been performed by examination of the reactivity of model intermediates. This study indicates that the re action path involves successive dehydrogenation, O/S exchange and dehydrohe terocyclization.
