Study of preferential solvation in mixed binary solvent as a function of solvent composition and temperature by UV-vis spectroscopic method
Preferential solvation of N-ethyl-4-cyanopyridinium iodide and 2,6-diphenyl-4(2,4,6-triphenyl-1-pyridino)phenolate [Reichardt's E-T(30) dye] has been studied in ethanol + tetrahydrofuran, ethanol + acetonitrile and acetonitrile + tetrahydrofuran binary mixtures as a function of temperature and composition of mixed binary solvents. It has been found that besides solute-solvent interaction, solvent-solvent interaction plays an important role in determining the solvation characteristics.
