| Abstrakt: | A solid acid, Cs2.5H0.5PW12O40, efficiently catalyzed hydration of 2,3-dimethylbut-2-ene in excess water at 343 K, while typical oxide-based catalysts such as Nb2O5, SiO2-Al2O3, TiO2-SiO2, and SO42−/ZrO2were almost inactive. The activity (per unit weight) of Cs2.5H0.5PW12O40was found to be higher than those of liquid acids like H3PW12O40and H2SO4, and of a commercial solid acid, H-ZSM-5, for hydration of cyclohexene. |
