1. A study has been made of the hydrogen-exchange reaction occurring when heavy sulfuric acid reacts with saturated cyclic hydrocarbons(cyclohexane, methylcyclohexane, 1,1-dimethyleyclohexane, 1,4-dimethylcyelohexane, 1-ethyl-4-merhylcyclohexane, eyclopentane, methylcyclopentane, and cis- and trans -decahydronaphthalenes). 2. It has been established that monocyclic hydrocarbons containing tertiary carbon atoms (methylcyclohexane, 1,4-d:methyloyclohexane, 1-ethyl-4-methylcyclohexane, and methylcyclopentane) undergo hydrogen exchange, equilibrium being established in a few hours at room temperature. 3. It has been Found that no hydrogen exchange is to be observed between heavy sulfuric acid and cis- and trans-decahydronaphthalenes, 4. It has been established that, when a mixture of a hydrocarbon containing a tertiary carbon atom with a hydrocarbon that does not contain a tertiary carbon atom is treated with heavy sulfuric acid, only the hydrocarbon containing the tertiary carbon atom takes part in hydrogen exchange. 1954 Consultants Bureau, Inc.
