ABSTRACT

Liquid liquid equilibria of three ternary systems, {glycerol + benzene + methanol}, {glycerol + benzene + ethanol}, and {glycerol + benzene + 1-propanol}, were measured at temperatures of (288.15, 298.15, and 308.15) K. The quality of the results was assured by the Othmer Tobias and Hand equations with the linear correlation factor (R2 greater than 0.98). The results were satisfactorily correlated with the UNIQUAC equation with total average deviations of 0.55 %, 0.69 %, and 0.42 %, respectively. Glycerol was demonstrated as a suitable solvent to separate the mixture of benzene and 1-propanol into each pure component, by combining two operations of conventional distillation and liquid extraction.
