"WebThe intrinsic basicity of the base and its adsorption energy within the zeolite are correlated. From this correlation, is possible to conclude that, in general, bases with proton affinities (PA) larger than 200 kcal mol-1 should lead to the formation of IPs, whereas bases with PA smaller than this value should form HB complexes.
