摘要: ABSTRACTExcess molar volumes and refractive index, refraction deviations isentropic compressibility changes in 1,4-dioxane + isobutyric acid binary mixtures (from 295.15 to 313.15) K. were calculated from experimental density, index sound velocity data presented previous work. Here, these values used test the applicability of correlative reduced Redlich–Kister equation as well their corresponding relative functions which are important reduce effect temperature and, consequently, reveal effects different types interactions. The results observations have been interpreted terms structural solvents. correlating recently proposed by Belda, has also applied present system order assess validity this give thermodynamic limiting partial quantities interesting evaluate solute–solvent interaction.
