p-Isopropylphenol was synthesized by catalytic transfer dehydrogenation with 5% Pd/C using 4-isopropylcyclohexenone as the materia1 and the hydrogen offer, industrial dipentene as the hydrogen acceptor and the solvent. The reactions were carried out directly under reflux condition. The effects of an amount of 5%Pd/C, the reaction time and reaction temperature were investigated. The optimal conditions of the synthesis were determined as follows: the mass ratio of 5%Pd/C to the material was 10:0.7, the reaction time was 30 min at reflux temperature. The yield of p-isopropylphenol was up to 87% u...
