STRUCTURE, H-1-NMR SPECTRA, THERMODYNAMICS, AND TRANSPORT-PROPERTIES OF MOLTEN-SALT SOLUTIONS .1. 4-METHYLPYRIDINIUM CHLORIDE AND 4-METHYLPYRIDINIUM IODINE

The H-1 NMR spectra of binary mixtures of 4-methylpyridinium chloride and 4-methylpyridinium iodide were measured as a function of temperatu re and composition over the entire composition range. Correlations wer e made between these spectra and thermodynamic and transport propertie s of the melts. The effect of hydrogen bonding on the melt's propertie s was assessed and a four ''component'' model was proposed to account for these properties. A pronounced ''mixed ion'' effect was observed i n the NMR spectra, but was barely discernible in the transport propert ies and completely absent in the thermodynamic properties.
