Abstract
The excess enthalpies, H(E), for mixtures of the nonionic amphiphile C 4H9OC2H4OH + water were measured by isothermal flow calorimetry at atm ospheric pressure and 10 temperatures over the temperature range T - T (lcst) = -0.1 to +32 K. (T(lcst) is the lower critical solution temper ature.) The H(E) data are reported and compared to literature values. The phase boundaries between the single- and two-phase regions, determ ined from the H(E) data, are also reported and compared to data from t he phase volume method and from the literature.
