Abstract

The difference in reactivity of solid α-LiAlO2 versus γ-LiAlO2, the former when in contact with molten benzoic acid will exchange Li+ for H+ and the latter will not, demonstrates that the Li+ cation in α-LiAlO2 is less acidic yielding the oxide more basic. Similarly when the surfaces of α-LiAlO2 and γ-LiAlO2 are contacted with the organic molecule isopropyl alcohol at similar temperature and conversion, the selectivity to base-catalyzed aldol condensation products are greatest with α-LiAlO2. Both examples demonstrate that the surface basicity depends on the environment of the O2- anion and the cation(s) to which it is bound.
