Fast and Quantitative Dehydration of Lower Alcohols to Corresponding Olefins on Mesoporous Silica Catalyst

摘要

Ethanol, 1-propanol, 2-propanol, and 1-butanol were quantitatively dehydrated to the corresponding olefins on mesoporous silica MCM-41 catalyst. The reaction rates were high and no deactivation was observed for 50 h. Two reaction routes were suggested: the intermolecular dehydration of alcohol and subsequent decomposition of ether and the direct dehydration of alcohol.
