摘　　要：研究了以松香胺希夫碱 铜配合物为催化剂催化H2O2氧化松香的情况.探索了H2O2浓度、溶剂、催化剂的用量、温度等因素对反应的影响 实验结果表明,在无水乙醇作溶剂,松香胺希夫碱 铜催化剂用量为2%情况下,温度对反应的影响最大 其次为H2O2的用量,而时间对反应的影响最小.通过正交实验得出最佳实验条件为:在松香与无水乙醇的质量比为1∶5,松香胺希夫碱 铜催化剂用量为2%情况下,反应温度80℃,35%H2O2的用量7ml,反应时间1h较理想.The synthesis of rosin amine schiff base-Cu~^(2+) complex and its catalysis for the oxidation of rosin by H_2O_2 were studied. The effect of reaction temperature, time, solvent and H_2O_2 concentration on the degree of conversion was discussed. The results showed that temperatures was the key affection factor for the oxidation reaction. Second factor was the concentration of H_2O_2.Optimal condition was:2% the rosin amine schiff base-Cu^(2+) complex, 10g rosin,5ml 35% H_2O_2 mixed at 80℃ in 50g(63ml) alcohol for 1h.
