摘要: Precise density and viscosity measurements on ternary solutions (polyhydroxy solute + NH4Br H2O) have been carried out over the temperature range (288.15 to 318.15) K at atmospheric pressure. Partial molar volumes, V2° infinite dilution Jones-Dole B-coefficients obtained from above data were utilized estimate transfer parameters (ΔtV2° ΔtB) for polyhydroxy solutes. The interaction coefficients values using McMillan–Mayer theory of solutions. Isobaric expansion second-order derivatives {(∂V2°/∂T)P, (∂2V2°/∂T2)P}, dB/dT also determined study effect temperature. These used understand kosmo-/chaotropic nature solutes cosolute which is helpful in rationalizing mixing effects due interactions between them these solutions, concomitantly keeping stereochemical differences view.
