摘要: Excess molar volumes of binary mixtures 1,2,3,4-tetrahydronaphthalene (tetralin) with benzene, toluene, ethylbenzene, n-propylbenzene, iso-propylbenzene, n-butylbenzene, tert-butylbenzene, and sec-butylbenzene over the whole mole fraction range were measured a continuous dilution dilatometer. All experimental values, except that benzene system, are negative. Flory theory its extended form, two-parameter method, used to describe volumetric properties. Theoretical prediction properties is discussed in terms efficiency segmental contact sites. It concluded method can improve greatly theoretical results.
