Solute–solvent and solvent–solvent interactions in binary solvent mixtures. Part 4. Preferential solvation of solvatochromic indicators in mixtures of 2-methylpropan-2-ol with hexane, benzene, propan-2-ol, ethanol and methanol

Abstract

The Dimroth–Reichardt ET(30) betaine dye, 4-nitroanisole, 4-nitroaniline and N,N-diethyl-4-nitroaniline have been used to study preferential solvation in binary mixtures of 2-methylpropan-2-ol with hexane, benzene, propan-2-ol, ethanol and methanol at 30 °C over the whole range of solvent compositions. A theoretical equation which takes into account the solute–solvent and the solvent–solvent interactions has been successfully employed to correlate the experimental values with solvent composition. The indicators have been used to compute the Dimroth–Reichardt ET(30), and Kamlet–Taft π*, α and β solvatochromic parameters of the mixtures.
