Objectives To prepare cyclohexene from cyclohexanol from cyclohexanol by an elimination method and to test for unsaturation in product. To introduce the method of purification for an organic liquid. Introduction The acid-catalyzed dehydration of an alcohol is an important method for the preparation of an alkene. It is also an example of an elimination reaction, which proceeds by a first order mechanism via an intermediate carbocation. In this experiment, cyclohexanol is dehydrated to cyclohexene n the presence of concentrated phosphoric acid: Distillation is employed in this experiment to synthesize and purify cyclohexene. The principle of distillation as a separation method is based on the difference in boiling points of substances. The identity and purity of the product can be checked by infrared spectroscopy and gas chromatography.
