In aqueous acidic media, picolinic acid, 2,2'-bipyridine and 1,10-phenanthroline promoted Cr(VI) oxidation of 1-butanol produces 1-butanal. 1-butanal is separated from mixture by fractional distillation. The anionic surfactant (SDS) and neutral surfactant (TX-100) accelerate the process while the cationic surfactant (CPC) retards the reaction. Combination of bipy and SDS is the best choice for chromic acid oxidation of 1-butanol to 1-butanal in aqueous media.
在酸性水介质中，吡啶甲酸、2,2'-联吡啶和1,10-菲咯啉促进铬(VI)将1-丁醇氧化生成1-丁醛。通过分馏从混合物中分离出1-丁醛。阴离子表面活性剂（十二烷基硫酸钠）和中性表面活性剂（聚氧乙烯辛基苯酚醚）加速该过程，而阳离子表面活性剂（十六烷基吡啶氯化物）则阻碍反应。在水介质中，联吡啶和十二烷基硫酸钠的组合是将1-丁醇铬酸氧化为1-丁醛的最佳选择。
