Title

Phase Equilibrium Behavior Of The Binary Systems Co 2 + Nonadecane And Co 2 + Soysolv And The Ternary System Co 2 + Soysolv + Quaternary Ammonium Chloride Surfactant

Abstract

Liquid phase and molar volume data were measured for the binary system CO 2 + soysolv at (298.15, 313.15, 323.15, 333.15, and 343.15) K and the ternary system CO 2 + soysolv + quaternary ammonium chloride surfactant at (298.15, 313.15, and 333.15) K, where the composition of soysolv to the surfactant is 99:1 wt % and 80:20 wt % on a CO 2-free basis. Data were collected stoichiometrically with a high-pressure Pyrex glass cell, where no sampling or chromatographic equipment is required. The accuracy of the experimental apparatus was tested with phase equilibrium measurements for the system CO 2 + nonadecane at 313.15 K. A pressure-decay technique was used to calculate the mass of CO 2 loaded into the equilibrium section of the apparatus, and its accuracy was verified with a blank nitrogen experiment. The generated data show that CO 2 modified soysolv is an effective transport medium for the quaternary ammonium chloride surfactant.
