Abstract 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.
