Partial Molar Volumes of Sodium Perfluoroalkanoates and Lithium Perfluoro-1-alkanesulfonates in Aqueous Solutions

Abstract

Abstract The densities of aqueous solutions of sodium perfluoroalkanoates, F(CF2)nCOONa (n=1–4, 6, 7) and lithium perfluoro-1-alkanesulfonates, F(CF2)nSO3Li (n=1, 4, 8) were measured at 25°C, and the limiting partial molar volumes were calculated. The assignment of group partial molar volumes is discussed.
