Notes: Abstract H3PW12O40 and its acidic cesium salts are catalytically active for pentane isomerization at ambient temperature. The influence of activation temperature and Cs content of the catalysts on their activity and selectivity have been investigated and discussed in relation to textural properties and surface acidity. H3PW12O40 and Cs2.25H0.75PW12O40 are superacidic as evaluated by measuring the rate constants of pentane isomerization at 35°C. Their acid strengths are in the range of H0=−13∼−12.4.
