Excess isentropic compressibilities were calculated from the experimental data. Excess enthalpies at T = 298.15 K are also included for the same binary mixtures. All these properties provide an insight into the nature of interactions operating on the present systems. Finally, the Prigogine-Flory-Patterson theory has been used to analyze the H E results and to estimate the isentropic compressibility values of the mixtures at T = 298.15 K.2015http://zaguan.unizar.es/record/5609710.1007/s10973-015-4797-4http://zaguan.unizar.es/record/56097oai:zaguan.unizar.es:56097JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY 122, 2 (2015), 851-861All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
