-
A natural polymer catalyst, sillca-supported chitosan palladium complex (abbr. asSiO2-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 1.01325×105 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 several times without much decrease in its catalytic activity.
