Liquid-liquid Equilibria of the Water- Acetic Acid-butyl Acetate System
ثبت نشده
چکیده
Experimental liquid-liquid equilibria of the water-acetic acid-butyl acetate system were studied at temperatures of 298.15±0.20, 303.15±0.20 and 308.15±0.20 K. Complete phase diagrams were obtained by determining solubility and tie-line data. The reliability of the experimental tie-line data was ascertained by using the Othmer and Tobias correlation. The UNIFAC group contribution method was used to predict the observed ternary liquid-liquid equilibrium (LLE) data. It was found that UNIFAC group interaction parameters used for LLE did not provide a good prediction. Distribution coefficients and separation factors were evaluated for the immiscibility region.

Effect of Magnetic Field on the Liquid-liquid Equilibria of (Water + Acetic Acid + Organic Solvent) Ternary Systems
The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...
متن کاملDesign and Optimization of Acetic Acid Dehydration Processes
Acetic acid is the most widely used aliphatic carbonic acid used as a reaction partner during the manufacture of acetic acid esters, or employed as a solvent in the production of cellulose acetate. Although acetic acid and water do not form any azeotrope, use of simple distillation to separate these two components is still not practical due to its high energy consumption rate. In this work, som...

متن کاملModeling of liquid–liquid equilibria of aqueous alcohol + salt systems using amodified NRTL
The modified NRTL (m-NRTL) model is used to represent the excess Gibbs free energy of aqueous (alcohol + electrolyte) solutions. In this work, the m-NRTL model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. The proposed extension is a modified of ...
