The four systems exhibit positive deviations from ideal behavior, and all data (p-T-x-y) were found to be thermodynamically consistent, The activity coefficients and the dimensionless function G(E)/RT of the solution were correlated with its concentration by different equations. An azeotrope was found in the mixture butyl methanoate (1) + ethanol (2) at T = 350.9 K and x(1) = y(1) = 0.088. The group contribution models ASOG and modified UNIFAC gave fair predictions.||URI:||http://hdl.handle.net/10553/52123||ISSN:||0021-9568||DOI:||10.1021/je00022a004||Source:||Journal of Chemical and Engineering Data[ISSN 0021-9568],v. 40, p. 1178-1183|
