Excess molar volumes of the mixture of tire-derived fuel with toluene and xylene between 298.15 and 323.15 K

From the measured density values of the mixtures between the tire-derived oil and toluene and xylene between 293.15and 323.25 K, the excess molar volumes were determined, and it was seen that the excess molar volumes calculated with the Redlich–Kister polynomial equation were in good agreement. It was determined that the excess molar volume showed a positive deviation at each temperature and that physical interactions between the components forming the mixture were dominant. It was seen that chemical forces were dominant due to intramolecular and intermolecular interactions such as charge-transfer complexes in the pyrolytic oil consisting of electron donor and electron acceptor components. It was observed that the physical and chemical forces between the components varied depending on the temperature, and therefore, the excess molar volume changes were not linear at 323.15 K.
