✦ Synopsis


Data on (liquid + liquid) equilibrium in (dimethyl phthalate + water), (diethyl phthalate + water), and (dibutyl phthalate + water) have been measured by direct analytical methods over the temperature range (283 to 323) K. Gas chromatography and spectrophotometric methods have been employed to determine the composition of the organic substances in the liquid phases. The water content in the organic liquid phases has been measured by means of the Karl-Fischer titration. A new l.l.e. measurement cell which allows samples to be analysed more easily and more precisely was constructed.

The experimental data have been fitted by means of the modified Wilson equation using the maximum likelihood method.

The osmotic coefficients of aqueous calcium chloride solutions were experimentally determined at T = 313.15 K by the isopiestic method. Magnesium chloride served as the isopiestic standard for the calculation of osmotic coefficients. The molality range covered in this study correspond to about 0.1 m

Consistent (vapour + liquid) equilibrium data for the ternary system (benzene + cyclohexane + anisole) at p = 101.32 kPa are reported. The results indicate that the mixture deviates positively from ideality and that only the minimum binary azeotrope (benzene + cyclohexane) exists. The activity coeff
