Surface tension calculation of mixed solvents with respect to solvent composition and temperature by using Jouyban-Acree model

Abstract

Applicability of a solution model, i.e. Jouyban-Acree model (JAM), for calculating surface tension of binary and ternary solvents at various temperatures has been shown employing experimental surface tension data collected from the literature. The accuracy of the model was evaluated by calculating average percentage deviation (APD) between calculated and observed values. The obtained overall APD (±S.D.) for JAM using binary solvent data were 4.06 (±4.27) and 8.07 (±9.78)%, respectively for correlative and predictive analyses. The corresponding values for the best similar model from the literature were 8.86 (±6.40) and 37.10 (±27.65)% and the mean APD differences between JAM and previously published model were significant (p<0.003). The capability of JAM for correlating surface tension of ternary solvents at various temperatures was also shown and the overall APD was 1.39 (±0.37)%. © 2004 Pharmaceutical Society of Japan.
