Excess molar volumes V-E, refractive index deviations Delta n(D), and viscosity deviations Delta eta of the ternary dimethyladipate + 2-butanone + 1-butanol and binary 2-butanone + 1-butanol systems are determined from the measured densities rho, refractive indices n(D), and viscosities eta. Viscosities and viscosity deviations of the binary dimethyladipate + 2-butanone system are also presented. Measurements are carried out at eight temperatures from (288.15 to 323.15) K and at an ambient pressure of 0.1 MPa. Instruments from Anton Paar were utilized: a digital vibrating tube densimeter type DMA 5000, RXA 156 refractometer, and SVM 3000/G2 digital Stabinger viscometer. Excess properties of the binary system were fitted to the Redlich-Kister polynomial equation, whereas for the ternary system, the Nagata-Tamura equation was applied. To try to comprehend the nature of the interactions between compounds that cause nonideal behavior in mixtures, FT-IR spectra of the binary constituents were collected at T = 298.15 K. V-E data of the investigated ternary system show both negative and positive deviations from the ideal behavior. On the other hand, viscosity changes are negative, while changes in refractive indices are positive over the entire concentration area at all investigated temperatures.
