| Abstract：The evaluation of the hydroxylation of phenol on complex-oxide catalyst was studied experimentally.The results showed that Cat9805 has a better selectiveity than that of Cat9808,but the ratio of CA/HQ less. Cat9808 has a mormal ratio of CA/HQ. Their catalytic activdity is close to other industrialiaed,catalysts. |
