| Abstract: | The synthesis of benzoic acid from benzaldehyde by KMnO4 oxidation in the presence of phase transfer catalyst with microwave irradiation was reported. The effects of reaction conditions such as microwave power, irradiation time and catalyst were investigated. The results showed that the optinal reaction conditions were as follows： 0.04 mol benzaldehyde, microwave power 750 W, irradiation time 10 min, 1.0 g TBAB, 4.0 g sodium carbonate, 4.2 g potassium permanganate. The yield of benzoic acid was 77.8 %. |
