摘　　要：甲苯氧化制备苯甲酸是验证芳烃侧链氧化反应的经典实验。本文通过一次性加入高锰酸钾、滴加甲苯、磁力搅拌等方法对该实验进行绿色化改进。该改进方法和缓可控、安全性高、产量较高,无需购买额外的试剂设备,就能达到比较理想的教学效果。The preparation of benzoic acid by toluene oxidation is the typical experiment about aromatic side chainoxidation. The methods of one time adding potassium permanganate, drop adding toluene and electromagnetic stirringwere employed to explore the green improvement about the experiment. The improved experiment is controlled andmild with high safety and high yield. And the improved experiment could also have better teaching effect without extrareagents and instraments.
