OSTI ID:7187428
Enthalpies of dilution of aqueous dodecyltrimethylammonium bromide from 323 to 498 K, of aqueous tetradecyltrimethylammonium bromide from 323 to 448 K, and of aqueous sodium chloride from 349 to 448 K have been measured using a flow calorimeter. The surfactant data are fitted using a nonlinear least squares minimization of a cubic splined surface. From these fits, changes in activity and osmotic coefficients with respect to temperature and also the relative apparent molar enthalpies and heat capacities may be calculated. Critical micelle concentration regions are obtained and compared to values obtained from conductance measurements. Pitzer's ion-interaction equation is fitted to the sodium chloride data, and the calculated relative apparent molar enthalpies are compared to literature values. This comparison demonstrates a high degree of reliability of data produced by the Albert-Wood calorimeter used in these studies. 44 refs., 18 figs., 10 tabs.
