Determination of temperature dependence of limiting activity coefficients for a group of moderately hydrophobic organic solutes in water
Original language description
Limiting activity coefficients in water were measured for 17 moderately hydrophobic compounds at several temperatures. Three experimental techniques, viz. Rayleigh distillation, IGS, and HSA, were alternatively employed. With the objective to establish the reliable temperature dependence of limiting activity coefficient, the activity coefficient values were combined with calorimetric data determined previously in our laboratories. This database was further supplemented with critically evaluated literature data. The 3-parameter equation assuming temperature independent heat capacity was found to represent available information adequately except for 1-butanol. For all the solutes, activity coefficient temperature dependence exhibits a maximum between 273and 373 K. As shown, by processing simultaneously the equilibrium and thermal data, consistent and accurate temperature dependence of activity coefficient can be obtained for the range 273 - 373 K even in cases of minimum underlying info
