ABSTRACT:
A method for forming dihydroDicyclopentadiene comprises mixing a source of dicyclopentadiene with at least one solvent and at least one reactive component in the presence of a source of hydrogen and a selective hydrogenation catalyst, the solvent and reactive component being readily separable from dihydroDicyclopentadiene, and the reactive component and catalyst favoring the formation of dihydroDicyclopentadiene over tetra hydro dicyclopentadiene.
