Apparent Molar Volumes of Calcium Nitrate in 1-Propanol + Water at 298.15 K

1999

The densities of 1-propanol + water + calcium nitrate mixtures have been measured with an oscillating-tube densimeter over a large range of concentrations of the salt and 1-propanol, at 298.15 K. From these densities, apparent molar volumes of calcium nitrate in 1-propanol + water mixtures have been calculated, and partial molar volumes at infinite dilution have been evaluated.

Isobaric Vapor−Liquid Equilibria for 1-Propanol + Water + Calcium Nitrate

1999

Isobaric vapor−liquid equilibria for all of the binary and ternary mixtures of 1-propanol, water, and calcium nitrate have been measured at 100.00 kPa using a recirculating still. The addition of calcium nitrate to the solvent mixture produced an important salt effect; the azeotrope was removed at salt mole fractions higher than 0.08. The three experimental binary data sets were independently fitted with the electrolyte NRTL model (Mock, B.; Evans, L. B.; Chen, C. C. AIChE J. 1986, 32, 1655−1664), and the parameters of Mock's model were estimated for each binary system. No ternary parameter was required. These parameters were used to predict the ternary vapor−liquid equilibrium using the sa…
