Kinetic data for oxidation of D-sorbitol to glucose by hexavalent chromium in aqueous medium and aqueous surfactant medium (SDS, TX-100) have been reported. Effect of promoter such as PA, bipy and phenanthroline on the reaction has been investigated. The reaction is performed under pseudo first order condition with an excess of substrate over the oxidant. The reaction is first order with respect to substrate and oxidant. The micelles have a catalytic effect on the reaction. Combination of phen and TX-100 produces almost twelve times increase in rate of oxidation.
已报道了在水介质和水相表面活性剂介质（SDS、TX-100）中六价铬氧化 D-山梨醇为葡萄糖的动力学数据。研究了促进剂如 PA、bipy 和菲咯啉对反应的影响。反应在底物过量的条件下在准一级条件下进行。反应对底物和氧化剂均为一级反应。胶束对反应具有催化作用。 phen 和 TX-100 的组合使氧化速率增加了近 12 倍。
