摘要：

The electrical conductivity, density, viscosity, and electrochemical window of four low-temperature molten salt systems (2:1 AlCl3-«-butylpyridinium chloride, 1:1 AlCl3-«-butylpyridinium chloride, 2:1 AlCl3-ethylpyridinium bromide, and 2:1 AlBr3-ethylpyridinium bromide) as well as their mixtures with benzene are reported, The nature of the interactions occurring as the melt is diluted with benzene were investigated using 1H and 13C nuclear magnetic resonance spectroscopy. The addition of benzene to the melts causes a decrease in the dielectric constant of the medium resulting in ion pair formation between the alkylpyridinium cations and the anions in the melt. No evidence was found for the formation of complexes between benzene and AlCl3 in the melt. © 1979, American Chemical Society. All rights reserved.
