Abstract

Solid-state 27Al and cross-polarization (CP) 13C magic-angle spinning nuclear magnetic resonance (MAS NMR) was used to characterise aluminas obtained by calcining basic aluminium succinate at different temperatures. In basic aluminium succinate, aluminium is in the tetrahedral coordination only. However, in both X-ray amorphous and γ-aluminas aluminium is in the tetrahedral and octahedral coordination. The intensity of the aluminium peaks is at a maximum for samples calcined at 700°C. 13C CP MAS NMR indicates the bonding of Al with carbon of the carboxylate group in basic aluminium succinate. Samples calcined at 400–870°C do not give 13C spectra.
