Abstract
Isobaric vapor-liquid equilibria were determined at 74.66,101.32, and 127.99 kPa for binary mixtures containing methyl propanoate + n-butyl alcohol by using a dynamic still with vapor and liquid circulation. No azeotrope was detected. The data were found to be thermodynamically c onsistent according to the point to point test. Application of the gro up-contribution models ASOG, UNIFAC, and modified UNIFAC to the activi ty coefficients at the three pressures studied gives average errors of less than 10%, 11%, and 3%, respectively.
