Lab 22: 4-Methylcyclohexene Abstract: We treated 4-methylcyclohexanol with phosphoric acid‚ and after purification we produced the end product 4-methylcyclohexene. We determined we had a pure product based on the results of the tests with Br2 and KMnO4‚ as well as the IR absorbtion spectrum of the final product. Purpose: The purpose of this experiment is to obtain pure 4-methylcyclohexene by reacting 4-methylcyclohexanol and phosphoric acid. Through distillation
