摘要： 利用3-氨丙基功能化的介孔SBA-15(APS-SBA-15)作为载体, 通过C—N共价键将8-羟基喹啉铜(Ⅱ)固定到APS-SBA-15孔道中, 制备了8-羟基喹啉铜(Ⅱ)功能化的SBA-15催化剂[Cu(Ⅱ)-Q-APS-SBA-15], 并将其用于以质量分数30%的过氧化氢为氧化剂的苯酚羟化反应中. 结果表明, Cu(Ⅱ)-Q-APS-SBA-15呈现出较高的苯酚转化率和苯二酚选择性.

Abstract: Firstly, copper(Ⅱ)-8-quinolinol ligands were introduced into the channels of 3-aminopropyl functionalized mesoporous SBA-15(denoted as APS-SBA-15). Then, the obtained copper(Ⅱ)-8-quinolinol functionalized SBA-15 materials[named as Cu(Ⅱ)-Q-APS-SBA-15] were tested as the catalysts for phenol hydroxylation by using H2O2(30%, mass fraction) as an oxidant. The reaction results indicate that Cu(Ⅱ)-Q-APS-SBA-15 was an excellent catalyst for this reaction, and over it a high conversion of phenol and a high selectivity to diphenol could be obtained.

Key words: SBA-15, Copper(Ⅱ)-8-quinolinol, Phenol hydroxylation, Catalytic performance
