Measuring and modeling of osmotic coefficients for LiNO3+2-naphthol+ethanol at 298.15K

Abstract The modeling purposes are achieved based on the experimental osmotic coefficients determination of lithium nitrate in LiNO 3 +2-naphthol+ethanol ternary system at 298.15 K. The experimental osmotic coefficients data are correlated using the Pitzer, the modified Pitzer equation by Esteso (PE) and the Pitzer–Simonson–Clegg (PSC) equations. The present calculations are performed for lithium nitrate electrolyte molalities ranging from 0 up to about 2.3 mol kg −1 in 2-naphthol and ethanol with different weight fractions, y =(0.25, 0.50, 0.75). Activity and vapor pressure data are also given.
