摘要: 本文报导了甲苯-三氯化铝-氯化氢体系的13C-NMR室温谱.实验证实在溶液中,不仅在甲苯分子与络合物分子之间,而且在络合物分子之间均存在着快速的化学交换.本文还解释了实验中出现的异常现象.

Abstract: The 13C-NMR spectra of the toluene-alumium chloride-hydrogen chloride system were measured at room temperature. The fast chemical exchange between toluene and its protonated complex as will as complexes themselves in the solution has been verified by means of the 13C-NMR spectra, some anomalous phenomena in the experiments are interpreted in this paper.

Key words: Chemical exchange, NMR, Carbonation, Prontonation
