Abstract
Osmotic coefficients are inferred from vapor pressure osmometry measurements that were performed for the ternary systems sodium glutamate-sodium thiocyanate-water varying the concentration of NaGlu and NaSCN (m(NaGlu) = 0.09, 033, 0.57 mol/kg and m(NaSCN) = 0.1-1 mol/kg) at T = 298.15 K and 310.15 K.

Abstract
Osmotic coefficients are inferred from vapor pressure osmometry measurements that were performed for the ternary systems sodium glutamate-sodium thiocyanate-water varying the concentration of NaGlu and NaSCN (m(NaGlu) = 0.09, 033, 0.57 mol/kg and m(NaSCN) = 0.1-1 mol/kg) at T = 298.15 K and 310.15 K. No strong interaction between glutamate and thiocyanate as suggested by theoretical MD and half-empirical quantum-chemical calculations (ab initio methods) can be concluded based on the experimental data. Absolute values of osmotic coefficients show mostly negative deviations from ideal state at both temperatures and for all sodium glutamate background concentrations. This is typical of a simple salt solution and a hint at only minor interactions between amino add and salt. (C) 2015 Elsevier B.V. All rights reserved.
