抄録

A solid acid, Cs<SUB>2.5</SUB>H<SUB>0.5</SUB>PW<SUB>12</SUB>O<SUB>40</SUB>, efficiently catalyzed hydration of 2,3-dimethylbut-2-ene in excess water at 343 K, while typical oxide-based catalysts such as Nb<SUB>2</SUB>O<SUB>5</SUB>, SiO<SUB>2</SUB>-Al<SUB>2</SUB>O<SUB>3</SUB>, TiO<SUB>2</SUB>-SiO<SUB>2</SUB>, and SO<SUB>4</SUB><SUP>2−</SUP>/ZrO<SUB>2</SUB> were almost inactive. The activity (per unit weight) of Cs<SUB>2.5</SUB>H<SUB>0.5</SUB>PW<SUB>12</SUB>O<SUB>40</SUB> was found to be higher than those of liquid acids like H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB> and H<SUB>2</SUB>SO<SUB>4</SUB>, and of a commercial solid acid, H-ZSM-5, for hydration of cyclohexene.
