▎ 摘　　要

NOVELTY - Preparing phenol by catalytic hydrogenation of guaiacol involves using n-dodecane as solvent, reacting guaiacol react with hydrogen under action of cobalt iron (CoFe)/reduced graphene oxide (rGO) catalyst at 260-320degrees Celsius, the hydrogen pressure is 0.5-3 megapascal, and the time is 0.5-4 hours to obtain phenol. USE - Method for preparing phenol by catalytic hydrogenation of guaiacol. ADVANTAGE - The method can reach conversion rate of guaiacol is 94%, and selectivity of phenol is 70.8%. The CoFe/rGO catalyst without reduction pretreatment is cheaper than noble metal catalyst such as platinum (Pt) and palladium (Pd).
