Abstract

Excess molar volumes (VE) and deviations in molar refractivity (ΔR) data at 298.15 K are reported for the binary systems diisopropyl ether + ethanol, diisopropyl ether + 2,2,4-trimethylpentane(isooctane) and ethanol + isooctane and also for ternary systems of diisopropyl ether + ethanol + isooctane by digital vibrating tube densimeter and a precision digital refractometer. The VE and ΔR were correlated with Redlich–Kister equation for binary systems and Cibulka equation for ternary system, respectively. Especially the ternary VE and ΔR were compared with the estimated values from the binary contribution model equations of Tsao–Smith, Kohler, Rastogi and Radojkovič.
