Abstract
A process for isomerizing endo-hydrogenated dicyclopentadiene to form the corresponding exo-isomer using a stable, pumpable liquid aluminum halide catalyst which includes steps of providing a first solution containing a hydrogenated dicyclopentadiene compound that is dissolved in a hydrocarbon solvent, adding a cosolvent to the first solution to form a second solution, adding an aluminum halide to the second solution, and isomerizing the hydrogenated dicyclopentadiene compound in the presence of dissolved aluminum halide which acts as a catalyst to produce the corresponding exo-isomer.
