Dehydration of the 2-methylcyclohexanol will take place via distillation with sulfuric acid on a microscale level to yield 1-methylcyclohexene and 3-methylcyclohexene. The proportions of these two products will then be determined by analyzing the graphs produced by a gas srmvision.com://srmvision.com
