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 ln σ 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 <THF (tetrahydrofuran) <IPA (isopropanol) < tertiary butanol based on the results of this study.
