▎ 摘  要

NOVELTY - Preparation of alpha -phenethyl alcohol comprises taking acetophenone as raw material, alcohol as hydrogen source, solvent and zirconia-silica/graphene hybrid material as catalyst, under atmospheric pressure, reacting at 45-90 degrees C for 2-10 hours, and distilling at 105-115 degrees C. The zirconia-silica/graphene hybrid material comprises mixed oxide and hybrid material. The mixed oxide comprises zirconia and silica at mass ratio of 1:5-20. The hybrid material has 0-2 wt.% graphene doping amount. USE - Method for preparing alpha -phenethyl alcohol (claimed). ADVANTAGE - The easy to operate method improves catalyst specific surface area, pore size, activity, selectivity and water resistance, ensures easy separation of liquid, reduces manufacturing cost, and improves economic efficiency.
