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

The modeling purposes are achieved based on the experimental osmotic coefficients determination of lithium nitrate in LiNO3+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.
