ABSTRACT
The surface tension of aqueous solutions of pyrrolidine and piperidine at temperatures of 20, 25, 30, 40 and 50 C have been measured over the mole fraction range. The surface tension value decreases significantly for the mixture rich in amine. Thermodynamic properties such as surface enthalpy and surface entropy for the systems studied were calculated from the experimental data.
