common Sophomore Organic Chemistry laboratory experiment that has great potential for further research is the acid catalyzed dehydration of simple alcohols. The classic dehydration of 2-methylcyclohexanol experiment that was introduced in Journal of Chemical Education in 1967 Taber(1967)JCE:44‚p620. The rather simple procedure of distilling an alcohol with an aqueous acid has spawned several investigations that have resulted in formal journal articles. At the same time‚ the experiment has retained

To ensure the reaction is complete an acid catalyst is commonly used. The catalyst is usually concentrated sulphuric acid. This experiment covered 4 techniques; they are distillation‚ refluxing‚ extraction‚ and esterification. Firstly‚ esterification and refluxing‚ the acid and alcohol are first warmed
