Enthalpies of dilution from 50 to 225°C of aqueous decyltrimethylammonium bromide

Enthalpies of dilution of aqueous decyltrimethylammonium bromide have been measured from 0.56 to about .005 mol-kg^–1 and from 50 to 225°C near the saturation pressure of water using a flow calorimeter. The changes of the stoichiometric osmotic and activity coefficients with temperature, the excess apparent molar heat capacity, and the apparent and partial relative molar enthalpies have been calculated from the data.
