摘要

在无溶剂条件下

以CuSO4和ZnO混合物为催化剂

空气中的氧气为氧化剂

催化氧化苯甲醇合成苯甲酸.考察了催化剂不同摩尔比、催化剂用量、氢氧化钠用量、反应时间与苯甲酸产率的关系

并对两种催化剂的反应机理进行了探讨.实验结果表明:在n苯甲醇∶nNaOH∶n催化剂=20∶25∶3

催化剂摩尔比nCuSO4∶nZnO=0.6

反应时间为90min的条件下

苯甲酸的产率可达到97.42%.反应过程中无废物排放

属环境友好型反应.

Abstract

Catalytic activity of the different mole proportions of Copper(Ⅱ) sulfate and Zinc oxide in oxidation of benzyl alcohol to benzoic acid with oxygen were studied under Free-Solvent method.Effect of different mole proportions of Copper(Ⅱ) sulfate and Zinc oxide

catalyst dosage

sodium hydroxide dosage and reaction time on yield of benzoic acid were investigated.The reaction mechanism was also discussed.It is found that with Free-Solvent method

the yield of benzoic acid can be 97.42% under reaction conditions of mole ratio of benzyl alcohol to catalyst to sodium hydroxide is 20∶25∶3

mole ratio of Copper(Ⅱ) sulfate to Zinc oxide is 0.6 and the reaction time is 90 min.The reaction was environmental friendly

and no waste was produced during the process.
