Vapor-Liquid Equilibria at 101.32 kPa Mixtures of Butyl Esters and Propan-2-ol

[摘要] References(17)Cited-By(1)The concentrations of the vapor-liquid equilibria have been measured in a small capacity recirculating still for the binaries composed of four butyl esters (from methanoate to butanoate) and propan-2-ol at a constant pressure of 101.32 kPa. VLE data were thermodynamically verified with the point-to-point test and the predictions made using several group-contribution models were acceptable but with some exceptions. An azeotrope was found for (x1butyl methanoate + x2propan-2-ol) at x1 = y1 = 0.038 and T = 354.9 K.
