Microcalorimetric Study of Some Short-Chain Nonionic Surfactants

Apparent enthalpies of mixing were measured for various surfactants of the general formula CH3–(CH2)n−1–(OCH2–CH2)mOH(CnEm) in aqueous solution at 25°C. From the experimental data the enthalpies of micellization were obtained. The results are briefly discussed.
