Abstract
H3PW12O40 and its acidic cesium salts are catalytically active for pen tane isomerization at ambient temperature, The influence of activation temperature and Cs content of the catalysts on their activity and sel ectivity have been investigated and discussed in relation to textural properties and surface acidity. H3PW12O40 and Cs2.25H0.75PW12O40 are s uperacidic as evaluated by measuring the rate constants of pentane iso merization at 35 degrees C. Their acid strengths are in the range of H -0 = -13 similar to -12.4.
