采用付-克烷基化反应,使水杨羟肟酸(SHA)键合到氯甲基化聚苯乙烯微球(CMCPS)表面,制得SHA功能化聚苯乙烯微球(SHA/CPS);再以SHA/CPS为配体,与过渡金属离子M(Co(Ⅱ)、Cu(Ⅱ)、Fe(Ⅲ)、Mn(Ⅱ))配位,制备了M-SHA/CPS配合物固体催化剂.研究了M-SHA/CPS在氧气非均相氧化乙苯中的催化行为.结果表明,M-SHA/CPS可有效地催化分子氧氧化乙苯.中心金属离子的电子结构对配合物催化性能有较大影响,其中Fe-SHA/CPS对乙苯氧化为EBHP的催化活性和选择性最高,在100℃下EBHP的含量高达14％.催化剂浓度、助剂四甘醇浓度和温度对Fe-SHA/CPS催化剂的活性和选择性有较大影响.此外,Fe-SHA/CPS具有较好的重复使用性.
