Abstract

Salt effect on the liquid phase equilibrium of the water-furfuryl alcohol-furfural system at 298.15 K was studied. The effects of salt concentration (1, 3 and 10% w/wNaCl) and type of salt (LiCl, KCl and RbCl) were investigated. The solubility and tie-line data of these systems were determined by experimental analysis. The results showed that addition of salt significantly affected the two-phase region of ternary system; the enlargement of two-phase region occurred with an increase of salt concentration in initial aqueous phase and the type of the salt in the following order: LiCl>NaCl>KCl>RbCl. Distribution coefficients and separation factors were also calculated. The reliability of the LLE experimental results was validated by the Othmer-Tobias equation, Hand equation and Bachman equation. NRTL was employed to correlate the results obtained by the modeling with the experimental data. Good correlation result was confirmed by the rmsd values of less than 0.3%.
