Abstract: An immobilized AlCl3 catalyst was first used to catalyze the isomerization of endo-tricyclodecane to produce adamantane. The AlCl3 catalyst immobilized on γ-Al2O3 exhibited high activity and selectivity at a low reaction temperature of 140 ℃, with endo-tricyclodecane conversion of 100% and adamantane selectivity of 17.7%, whereas the AlCl3 catalyst immobilized on SiO2 showed very low adamantane selectivity of almost zero.

Key words: alumina, immobilized aluminium chloride, tricyclodecane, isomerization, adamantane
