Abstract

Ternary phase equilibrium data for ethanol-water-1-hexanoic acid and 1-nonanoic acid were experimentally obtained with a view to evaluate the possibility of separation of ethanol from aqueous solutions by distributing each between water and ethanol phases. The mutual solubility curves, tie lines and plait points were constructed from the experimental results. Distribution coefficients and separation factors were computed for these systems. Hand’s method was used to correlate tie lines and to calculate coordinates of plait points. Tie line data were satisfactorily correlated by the Othmer-Tobias method on a mass fraction basis.
