Abstract The preparation of cyclohexene is a classic organic chemical experiment. In this experiment, anhydrous calcium chloride is used to remove the tiny bit of cyclohexanol in organic phase. However, there is no literature to prove that calcium chloride has good abilities of removing cyclohexanol, and experimental studies are required. This paper also compared the performance of calcium chloride to adsorb ethanol and isoamyl alcohol, in order to analyze its abilities of removing alcohols. The results show that calcium chloride can remove ethanol very well. While the ability of removing cyclohexanol and isoamyl alcohol is very weak and the adsorption takes a long time. This paper can be used as supplementary materials to the teaching experiment and can provide guidance for the experiment researchers.
