The kinetic behavior of tetrahydrotricyclopentadiene (THTCPD) isomerization was studied by using two kinds of chloroaluminate ionic liquid (IL) catalyst with different Lewis acidity. THTCPD isomerization pathway was discussed under the different temperature and time as reaction parameters using IL catalysts consisting of 1-butyl-3-methylimidazolun chloride $(BMIC)/AlCl_3$ with low acidity and pyridine hydrochloride $(PHC)/AlCl_3$ with high acidity. The conversion of THTCPD isomerization increased with increasing Lewis acidity of IL catalyst. The THTCPD isomerization pathway changed as a function of reaction temperature and catalyst acidity. In the case of $BMIC/AlCl_3$ IL catalyst, THTCPD isomerization pathway was similar to that of using conventional $AlCl_3$ catalyst. However, two different types of additional pathways (endo, exo, endo-NB ${\rightarrow}$ exo, exo, endo-NB ${\rightarrow}$ exo, exo, exo-NB and endo, exo, endo-NB ${\rightarrow}$ exo, exo, endo-NB ${\rightarrow}$ exo, exo, exo-CP) were appeared when using $PHC/AlCl_3$ IL catalyst.
