摘 要:高锰酸钾氧化环己醇制备己二酸实验,是高校基础有机化学实验课普遍开设的经典项目之一。学生实验过程中容易出现冲料、产品发黄等现象,导致实验效果不佳。梳理了合成过程中常见的6个问题,并进行了深入探讨,提出了解决方法,设计了实验改进方案。新方案学生实验产率普遍大于65%,产物纯度较高。Being as a classic item of fundamental organic chemistry experiment course in universities,the experiment for adipic acid preparation is usually carried out through oxidation of cyclohexanol by potassium permanganate.However,because of the bursting out of reactants and yellow products phenomenon appeared during the students operating,experiment effects were often not very well.In this present work,six problems occurred frequently during the synthesis process were analyzed and discussed deeply.Also,some solution approaches were proposed and the improved experimental project was further designed.The practice result indicated that this new method could make greater improvement with the experimental rate of>65%and products of high purity.
