Viscosities (ƞ) of solutions of 1- propanol and 2-propanol have been determined in aqueous systems of varying composition (0.16-3.64 mol dm-3) at 298 K. The ƞ/ƞ0 data have been analyzed in the light of reduced Jone-Dole equation ƞ/ƞ0 = BC+1. The results in the regards to solute-solvent interaction in aqueous solutions of both the alcohols have been discussed in the terms of the value B. The result of study reveals that both the alcohols behave as the structure makers in the water. The result shows that solute-solvent type interaction of same magnitude exists in water-alcohol system.

Activity coefficients at infinite dilution have been determined by gas–liquid chromatography for nine hydrocarbons solutes in cyclopentanol, cyclohexanol, cycloheptanol, benzyl alcohol, and n-heptanol at 25 °C. Experimental results for cyclopentane and cyclohexane in cycloalkanols compare favourably with the values obtained by extrapolation to infinite dilution of activity coefficient data calculated from Benson et al.'s static (vapour–liquid equilibrium) measurements. Some characteristics of the solute–solvent interaction in the systems are discussed in light of statistical approaches (thermal and athermal contributions).

The present study deals with experiments so as to highlight the solute (drug nimesulide) - solvent(water) interactions and related modifications in case of the presence of hydrotropic agents at different temperatures T(=298.15 to 313.15)K. Density and viscosity values of nimesulide have been determined in water in (0.1, 0.2, 0.4, 0.6, 0.8, 1 and 2) mol dm-3aqueous solutions of hydrotropic agents (sodium benzoate, sodium salicylate, sodium bromide and nicotinamide) at temperatures 298.15, 303.15, 308.15 and 313.15 K where as the solubility was studied at 308.15 K. From the density values, the limiting partial molar volumes and expansibilities have been calculated. The experimental viscosity values have been analyzed in terms of jones-dole equation and on the basis of transition theory for relative viscosity.
