ABSTRACT
Surface tensions of dilute solutions of cyclohexane, hexane, heptane, and nonane in benzyl alcohol were measured at various temperatures. Surface mole fractions were obtained from an extended Langmuir model. The results show that all of alkanes are surface active in benzyl alcohol and that their surface mole fractions are higher than their bulk mole fractions. The lyophobicity of solutes decreases with increasing temperature.
