Title: Dehydration of 2-methylcyclohexanol
Name: Sariana Stennis
Lab time: Wednesday 8:00am
Date: January 31, 2017
Introduction:
Dehydration occurs when water is removed from a molecule and subsequently forms a carbon-carbon double bond2. Dehydration can be used in the making of food preservatives1. In this experiment, 2-methylcyclohexanol is dehydrated and the formation of three products is possible: 1-methylcyclohexene, 3-methylcyclohexene, and methylene cyclohexane. In this case, 1-methylcyclohexene is expected.

Prior to the experiment, the sand bath was preheated and was monitored to be between the temperatures of 140°C and 160°C. Granulated Drierite® was funneled into a Hickman still with a straw until the bottom was about half full. No granules were observed to be stuck to the ring. A
