N-羟基马来酰亚胺-苯乙烯共聚物催化苯甲醇r氧化的研究

摘要

本文合成了N-羟基马来酰亚胺与苯乙烯共聚物P(HOMI/St),并以P(HOMI/St)/Co(Ⅱ)催化分子氧氧化苯甲醇制备苯甲醛,考察了反应温度、P(HOMI/St)用量、氧气压力等因素对反应的影响.实验表明,在优化条件下,苯甲醛的产率可达26%.催化剂重复使用4次,仍保持良好的催化活性.%The catalyst P(HOMI/St)was prepared. The oxidation of benzyl alcohol to benzaldehyde was achieved by P(HOMI/St)/Co(Ⅱ)as a catalyst,and the impact factors such as reaction temperature,the dosage of P(HOMI/St)and O2 pressure were studied. Under the optimized conditions,benzaldehyde yield reached 26%. The catalyst was recycled 4 times and remained good catalytic ac-tivity.
