介绍了在１０％和３０％的氢氧化钠中用聚乙二醇相转移催化苯甲醛的歧化反应。该反应能使苯甲酸的产率提高到９０．５％和９８．３％。同时还报道了在非相转移催化条件下，苯甲醛在１５％至２５％的氢氧化钠中，进行歧化反应的实验结果。
The disproportionation of benzaldehyde catalyzed by polyethylene glycol phase transfer in 10% and 30% sodium hydroxide is described. The reaction can increase the yield of benzoic acid to 90.5% and 98.3%. The experimental results of disproportionation of benzaldehyde in 15% to 25% sodium hydroxide under non-phase transfer catalysis were also reported.
