【 摘 要 】

References(31)Cited-By(7)Isobraric p-T-x-y values for four binary mixtures composed of several butyl esters (from methanoate to butanoate) with n-propanol at 101.32 kPa have been measured using a dynamic method. All mixtures presented positi ve deviations from ideality and they were found to be thermodynamically consistent with the point-to-point test, being then correlated with suitable equations. An azeotrope at x1 = 0.300 and T = 363.7 K was found for the mixture (x1, butyl methanoate + x2 n-propanol). The group contribution models gave acceptable estimations for the γi values.
