Abstract: 以H2O2为氧源,研究了歧化松香胺Schiff碱-铜配合物催化苯乙烯的氧化反应,探讨了溶剂种类、催化剂用量、氧化剂用量、反应温度及反应时间对催化氧化反应的影响。结果表明,催化氧化反应的较佳条件是:以1,4-二氧杂环己烷为溶剂,苯乙烯5.000 g,催化剂Schiff碱-铜配合物用量为苯乙烯质量的0.5%,质量分数为30%的H2O2 15 mL,80℃反应6 h。苯乙烯转化率为93.3%,主产物苯甲醛的收率和选择性分别为66.8%和71.7%。The performance of cupric complex of disproportionated rosin amine Shift base on catalyzing oxidation of styrene by H2O2 has been investigated. Factors affecting oxidation, such as solvents, temperature, reaction time, dosage of catalyst and the ratio of oxidant to alkene have been investigated. The optimum reaction conditions were: 5.000 g styrene with 15 mL 30 % H2O2 at 80℃ for 6 h in the presence of 0.5 % cupric complex in 1,4-dioxane. The conversion of styrene was 93.3 % , the yield and selectivity of benzaldehyde were 66.8 % and 71.7 %, respectively.
