CuAlg-CuTIPP was synthesized through the reaction between CuCl2 and NaAlg-CuTIPP that obtained by dispersing Cu-TIPP in sodium alginate. The hydroxylation of phenol was explored by using H2 O2 as the oxidant and CuAlg-CuTIPP as the cata-lyst. The results showed that the catalytic activity of CuAlg-CuTIPP was higher than copper alginate,the yield of dihydroxybenzene was increased by 9%,the conversion rate of phenol reached 40. 2%,the rate between catechol and hydroquinone nearly reached 4∶5.
