Prediction of Liquid-Liquid Equilibria of Binary Systems Containing Alcohols Using EoS-GE Models

Polymer Gel-Liquid Equilibria Using Uniface-FV

Based on Gibbs-Duhem law and using UNIFAC-FV computer algorithm, the activity of polymer component in polymer-solvent systems is determined. The variation of activity of components with concentration at different temperatures are used to find the equilibrium concentration, UCST, and LCST for the systems. Also by generalization of the method, Gel-Liquid equilibrium is studied in some three c...

Determination of Binary Vapor Liquid Equilibria (vle) of Reactive Systems

The simulation of reactive distillation processes requires binary phase equilibrium data and information about the reaction kinetics and equilibrium. The phase equilibrium data for the binary reacting sub-systems are difficult to measure experimentally since the products of reaction affect the binary equilibrium as soon as they are formed. A novel apparatus has been constructed to measure these...

Biaxial liquid-crystal elastomers: a lattice model.

We present a simple coarse-grained lattice model for monodomain biaxial liquid-crystal elastomers and perform large-scale Monte Carlo simulations in the proposed model system. Orientational ordering--uniaxial or biaxial--reflects in sample deformations on cooling the system. The simulation output is used to predict calorimetry data and deuterium magnetic resonance spectra.

Analytical applications of liquid-liquid phase equilibria: analysis of binary mixtures of chemically similar components.

A new, simple and rapid method based on the principle of liquid-liquid phase equilibria has been developed for the analysis of binary mixtures of chemically similar organic compounds. The method does not require elaborate instrumentation and can be used to analyse mixtures of members of homologous series. The application of the method has been illustrated by analysing binary mixtures of n-hexan...
