The reaction of pentane to 2-methylbutane was carried out at 0 °C over solid super acid catalysts which were prepared by treatment of various metal oxides with SbF<SUB>5</SUB> under different conditions, and the preparation conditions that affect the catalytic behavior of the catalyst were examined. Among the different base metal oxides, TiO<SUB>2</SUB>–ZrO<SUB>2</SUB> became the most active catalyst when treated with SbF<SUB>5</SUB>. The maximum conversion to 2-methylbutane which appeared in the reaction of pentane was high when a base metal oxide was treated with SbF<SUB>5</SUB> at a low temperature, and also when the reaction temperature was low. At the maximum conversion, the selectivity of the catalysts for the skeletal isomerization was almost 100%. As the reaction of pentane proceeded, the catalytic activity for the skeletal isomerization to 2-methylbutane was decreased but that for the formation of 2-methylpropane from 2-methylbutane was increased. The reaction mechanism is briefly discussed.
