Excess enthalpies of binary mixtures of ortho-, meta-, para-structural isomers containing aliphatic group

摘要: To obtain further systematic information for the isomer systems, excess molar enthalpies binary (o + m), p), (m p)-isomers of methoxymethylbenzene, ethylmethylbenzene, diethylbenzene, chloromethylbenzene, tolunitrile and fluorobenzonitrile, tolylacetonitrile were measured at 298.15 K. In this article, results are discussed compared with those previous works. The systems in different solid liquid states when pure component o-/m-tolunitrile, fluorobenzonitrile was titrated into prior p) or mixtures. A series calculation interaction energies (IE) between isomers carried out pair molecules by ab initio MO Gaussian 09. Correlations a fraction x = 0.5 intermolecular energy discussed.
