Nuclear magnetic resonance studies of molten salts. Progress report 1 January-31 December 1983
This report describes work in the areas of the measurement and interpretation of 13C NMR chemical shifts of room temperature molten salts of various composition formed from aluminum chloride and 1-methyl-3-ethylimidazolium chloride; the measurement and interpretation of 25Al NMR lineshapes as a function of temperature and melt composition; the NMR study of the reaction of acidic AlCl3/1-methyl-3-ethylimidazolium molten salt with dissolved chlorine; and the redistribution of halide on aluminum during the mixing of acidic chloride and bromide melts in acetonitrile solvent. As part of the study of the effect of temperature on the 27Al NMR lineshapes of the molten salts, a computer program is given which uses a matrix method to simulate NMR lineshapes as a function of chemical shifts and exchange rates.
