| Abstract |
Solubilities of triethylamine in aqueous tetraethylammonium chloride solutions were measured at 20, 25, and 35degreesC. The molalities in Et4NCl of the aqueous solvents ranged from 0.03 to 1 mol-kg(-)1. The data were evaluated from density measurements using a vibrating-tube densimeter. At each temperature, least-squares method was used to fit experimental density data points to double polynomial equations of various degrees. Triethylamine molalities of the saturated aqueous phases were estimated by extrapolation from those equations. Experimental data were interpreted in terms of hydrophobic and electrostatic perturbed domains in the hydration shells of the noneleceory and of the cation of the salt, as a function of temperature and salt concentration. The conclusions obtained are consistent with previous volumetric studies. |
