LLE prediction by LSER for water + propionic acid + hydrocarbon systems

The accurate interpretation of phase equilibria and thermodynamic properties for multi-component mixtures is a fundamental key to improve liquid –liquid equilibria technique.We investigated measurement of the LLE of three ternary systems of water + propionic acid + hydrocarbon (cyclohexane ,methylcyclohexane and toluene) at 303.2 K under atmospheric pressure in our laboratory previously, and tie lines data was determined. For a comparison of the extracting capabilities of studied organic solvents (hydrocarbons), the experimental distribution coefficients and separation factors were obtained and reported in literature [1].
