Abstract

A method for producing adamantane includes the steps of preparing a catalytic composition including an acidic ionic liquid and a co-catalyst and subjecting a tetrahydrodicyclopentadiene-containing component to isomerization in the presence of the catalytic composition to form adamantane. The acidic ionic liquid includes aluminum chloride and a quaternary onium compound selected from the group consisting of a quaternary ammonium halide, a quaternary phosphonium halide, and a combination thereof. The co-catalyst is an oxygen-containing reagent.
