β¦ Synopsis
Studies on the solvatochromic behaviour of N-methyl-4-and N-methyl-2-[(4-dimethylaminophenyl)iminomethyl]pyr-
idinium iodide dyes in a variety of solvents and the preferential solvation of the former dye in binary mixtures of protic and non-protic solvents are presented and interpreted in terms of solute-solvent and solvent-solvent interactions.

The preferential solvation of neutral and ionic organic species (phenol, nitroanilines, N-methylbutyramide, 1,4-dioxane, acetate and tetraalkylammonium ions) in binary solvent mixtures (aqueous CH 3 CN, DMSO, EtOH, 1-PrOH, CH 3 CON(CH 3 ) 2 ; CH 2 Cl 2 /Et 2 O; 1,4-dioxane/benzene; cyclohexane/THF)
The use of chemical probes for the characterization of chemical properties is explored for aprotic binary solvent mixtures. The solvatochromic indicators N,N-diethyl-4-nitroaniline, 4-nitroanisole, 4-nitroaniline and 4nitrophenol were used to characterize binary solvent mixtures of a polar aprotic h
The use of chemical probes for the characterization of chemical properties was explored for completely non-aqueous aprotic binary solvent mixtures. The Dimroth-Reichardt E T (30) betaine dye, 4-nitrophenol, 4nitroanisole, 4-nitroaniline and N,N-diethyl-4-nitroaniline were used to study preferential
