Picolinic acid, 2,2'-bipyridine and 1,10-phenanthroline promoted Cr(VI) oxidation of D-galactose to D-galactonic acid in three representative aqueous micellar media has been studied. The anionic surfactant (SDS) accelerated the rate of reaction while the cationic surfactant (CPC) and neutral surfactant (TX-100) retarded the reaction rate. Combination of bipy and SDS is the best choice for chromic acid oxidation of D-galactose to D-galactonic acid in aqueous media although 1,10-phenanthroline is best promoter in absence of micellar catalyst.
研究了吡啶酸、2,2'-联吡啶和 1,10-菲啰啉在三种典型的胶束水介质中促进 Cr(VI)氧化 D-半乳糖为 D-半乳糖酸的反应。阴离子表面活性剂（SDS）加速了反应速率，而阳离子表面活性剂（CPC）和中性表面活性剂（TX-100）则减缓了反应速率。尽管在没有胶束催化剂的情况下，1,10-菲啰啉是最好的促进剂，但在水介质中，使用 bipy 和 SDS 的组合是 Cr(VI)氧化 D-半乳糖为 D-半乳糖酸的最佳选择。
