Abstract
A process for isomerization of tetrahydrodicyclopentadiene using a supported acidic ionic liquid as catalyst is provided. In the presence of the supported acidic ionic liquid, endo-tetrahydrodicyclopentadiene is isomerized to exo-tetrahydrodicyclo-pentadiene, wherein the supported acidic ionic liquid includes a porous support and an acidic ionic liquid, and the acidic ionic liquid includes an aluminum halide, and a quaternary ammonium halide or a quaternary phosphonium halide. The porous support is impregnated with the acidic ionic liquid. Furthermore, under different reaction conditions, the exo-tetrahydrodicyclopentadiene product can be isomerized to adamantane in the presence of such a supported acidic ionic liquid.
