With the model proposed here, a procedure can be designed to correlate properties and estimate parameters by successive steps in the order (x, c(P)(E)) ->-> (x, h(E)) ->-> (x, g(E)), applied here to a set of binary P systems for which experimental data already exist for these properties. Some of the steps can be omitted if the values for some of these properties are not available. The practical application is carried out on a set of binary systems of (dialkylcarbonate + alkane) for which data have been found for the three quantities. However, new experimental values of h(E) and g(E), obtained isobarically, are also provided for the systems considered necessary to verify the model. The results of this application show a good correlation for these quantities, improving on the results of previous models of NRTL and UNIQUAC.||URI:||http://hdl.handle.net/10553/49705||ISSN:||0888-5885||DOI:||10.1021/ie0707366||Source:||Industrial and Engineering Chemistry Research[ISSN 0888-5885],v. 46, p. 7353-7366|
