Abstract: Method and catalyst for producing methylbenzyl alcohol from ethanol by catalytic conversion. A route and corresponding catalysts for directly producing methylbenzyl alcohols through catalytic conversion starting from ethanol, providing an important alternative route for increasing the production of aromatic oxygenates. The selectivity of the methylbenzyl alcohols is up to 60%. At the same time, the prepared catalysts have excellent stability. Moreover, this innovative reaction route produces hydrogen as co-product without CO, thus can be directly used in chemical reactions and fuel cells. In addition, the route also produces high carbon number alcohols which can be used as fuels or oil additives to partially replace petroleum-based products, thus partly reducing the dependence on petroleum.

Abstract: Methods and catalysts for producing benzyl alcohol and homologues thereof from short-chain alcohols by catalytic conversion are disclosed. The methods and catalysts develop a new route for benzyl alcohols and ethyl benzyl alcohols production through cross coupling-aromatization reaction using short-chain alcohols as reactants and provide corresponding catalysts required for the above catalytic reaction. It is emphasized on a single bed catalyst to produce benzyl alcohol and its homologues in one step, and is expected to become an important alternative route for the production of benzyl alcohol and its homologues. A route and corresponding catalysts for directly producing benzyl alcohol and ethyl benzyl alcohol through coupling-aromatization reaction starting from low carbon alcohols are provided. The selectivity of the benzyl alcohol is up to 35%, and the total selectivity of the ethyl benzyl alcohol is up to 11%.
