The Surface Tension of Mixtures of Methanol, Acetonitrile, Tetrahydrofuran, Isopropanol, Tertiary Butanol and Dimethyl-Sulfoxide with Water at 25°C

Abstract Surface tension data of binary mixtures of methanol, acetonitrile, tetrahydrofuran, isopropanol, tertiary butanol and dimethylsulfoxide with water have been measured. Best fit polynomal functions are reported for in [sgrave] vs. volume fraction of an organic modifier. The reported data is precise and accurate to about 2% and is consistent with the available literature data. The sequence of eluotropic strength based on the solvophobic theory in RP-HPLC should be dimethylsulfoxide < methanol < acetonitrile
