超声相转移催化氧化环己醇合成己二酸的实验研究

Experimental Study on the Synthesis of Adipic Acid from Cyclohexanol with Ultrasonic Phase Transfer Catalyzer

研究了用 30%的硝酸氧化环己醇合成己二酸。实验结果表明,用聚乙二醇作相转移催化剂,在功率为 50W的超声波作用下, 30%浓度的硝酸氧化环己醇,己二酸的产率可达到 46%。研究发现,氧化过程中尾气中NO2 的浓度明显减小,相转移催化剂和超声波辐射作用对反应有重要作用。

The synthesis of adipic acid by oxidizing cyclohexanol with nitric acid of 30% was investigated. The results showed that the yield of adipic acid could achieve to 46% when the ultrasonic power was 50W and polyethyleneglycol was used as ultrasonic phase transfer catalyzer. It was observed that the concentration of NO2 in the gas emission decreased greatly during oxidation and the phase transfer catalyzer as well as ultrasonic played important role in the reaction.
