摘要

<,正,>, A natural polymer catalyst, sillca-supported chitosan palladium complex （abbr. asSiO,2,-CS-Pd） was found to catalyze the hydrogenation of phenol and cresols to correspond-ing cyclohexanones in high yield and 100% selectivity at 70℃ and 1.01325×10,5, Pa mildconditions. N/Pd molar ratio in the complex, temperature and solvents have much infiuenceon the reaction. The reactivity order of reactants was found to be: phenol ,>,m-,>,p-,>,o-cresol. The catalyst is stable during the reaction and could be repeatedly used for severaltimes without much decrease in its catalytic activity.
