Conclusions
-
1.
The catalytic activity of a series of solid carriers, characterized by various “acidities,” was studied in the isomerization of terpene hydrocarbons. The experimental data agree with the assumption that the catalytic activity is due to protonic-acid centers on the surface of the carriers.
-
2.
The catalytic activity of solid carriers is suppressed when they are modified with small additions of polar substances (for example, polyethylene glycol), which form hydrogen bonds with the hydroxyl groups of the carrier. The catalytic properties of solid carriers decrease when they are impregnated with nonpolar liquid phases.
