Surface tension of the dimethylsulfoxide/thiophene system at 298.15 K

TLDR: In this article, the surface tension of dimethylsulfoxide (1) + thiophene (2) was determined over the whole composition range at 298.15 K. The densities have been determined with a vibrating tube densimeter and the surface tensions by the differential capillary rise technique.

Abstract: Densities and surface tensions of dimethylsulfoxide (1) + thiophene (2) were determined over the whole composition range at 298.15 K. The densities have been determined with a vibrating tube densimeter and the surface tensions by the differential capillary rise technique. Negative excess surface tensions were observed. From the different equations existing in the literature for estimation of surface tensions of mixtures we have used the equations due to Rice and Teja [1] and Winterfeld, Scriven and Davis [2]. The Rice and Teja's Equation gives better results.
