Butane reactions on SO~(2-)_4/ZrO_2 type solid superacids at ambient temperature were studied. The butane isomerization selectivity is higher than 95% while the total reaction conversion is lower than 50%. The rate of the butane isomerization reaction follows the rate law of a first-order reversible reaction. The reaction conversion, rate constant and activation energy of the isomerization reaction are dependent on the superacidity of the solid catalysts. As the H_o of the catalysts is increased, the reaction conversion and rate constant are increased and the activation energy is decreased. The butane isomerization at ambient temperature is a good probe reaction for the characterization of solid superacidity.
