ABSTRACT
Surface tensions of binary mixtures of N-methyldiethanolamine and triethanolamine with ethanol were determined at (15 to 40) deg C over the entire range of concentrations to analyze the influence of both variables. The Redlich Kister equation was employed to fit surface tension deviation obtained from experimental values.
