摘要：

Structure and properties of binary chloroaluminate ionic liquids and investigations on reaction mechanisms in ionic liquids with electron paramagnetic resonance spectroscopy was studied. The first resolved NMR spectra of a binary chloroaluminate ionic liquid was obtained by Osteryoung. Carper applied 13C relaxation methods to study NaCl buffered Cl/AlCl3 mixtures and investigated the interaction. Hydrogen bonding in basic imidazolium chloroaluminates was also studied with the help of H ROESY NMR. The results presented indicate that the understanding of bulk structure and speciation of ionic liquids has grown tremendously and that magnetic resonance spectroscopy has played a major part in this effort. It should be noted that for obtaining correct results, enough examination should be applied to the experimental setup and preparation of the system under study.
