Cyclohexane dehydrogenation
WebNov 1, 2008 · Dehydrogenation of methylcyclohexane to toluene is a method for hydrogen storage in the form of liquid organic hydrides. The efficiency of the dehydrogenation reactions and the quantity of products depend on the catalyst used. WebNaphthene derivatives can also be dehydrogenated—alkyl derivatives of cyclohexane usually dehydrogenate at 480-500 °C (895-930 °F). In the presence of catalysts, cyclohexane derivatives are converted into aromatic derivative—reactions of this type are prevalent in catalytic cracking and reforming.
