SYNTHESIS OF TERPINEOL FROM -PINENE CATALYZED BY TCA/Y-ZEOLITE

The hydration of -pinene has been studied in the presence of TCA/Y-Zeolite catalyse. The catalyst was prepared by impregnating trichloroacetic acid (TCA) on support of Y-Zeolite. The TCA/Y-Zeolite catalyst converted -pinene into hydrocarbons, while the TCA/Y-Zeolite catalyst was active and selective for producing alcohols, with a conversion of 66% and showed 55% selectivity for -terpineol at 10 min. The reaction taken place in a solid–liquid mode and most of the -terpineol is extracted out by the organic phase during the course of the reaction. TCA/YZeolite was found as good catalyst for hydration of -pinene to produce -terpineol.
