TERNARY LIQUID EQUILIBRL4 : METHANOL-WATER-ESTERS By R. JAGANNADHA RAO and C. VENKATA RAO

Mutual solubility and tie-line data are presented for four ternary liquid systems containing methanol, water and n-butyl acetate, pentyl acetate, ethyl propionate and ethyl butyrate as solvents at 30". For comparison, equilibrium data reported in the literature for the system methanolwater-ethyl acetate at 20" have been plotted on the saturation isotherm, equilibrium distribution and selectivity diagrams. The tie-line data for all the systems are satisfactorily correlated by the methods of Hand and Othmer-Tobias, and the plait points are located by the method of Treybal, Weber h Daley. For all the systems, it is found that the distribution of methanol is in favour of the aqueous phase. Although the distribution coefficient is higher for ethyl acetate, ethyl butyrate is found to be the most selective of the solvents studied.
