Densities and viscosities for the ternary system of cyclopropanemethanol (1) + 2, 2, 4-trimethylpentane (2) + decalin (3) and corresponding binaries at T = 293.15–323.15 K

Abstract

ABSTRACTDensities (ρ) and viscosities (η) of a ternary system cyclopropanemethanol (1) + 2,2,4-trimethylpentane (2) + decalin (3) and three corresponding binary systems were measured at temperatures from 293.15 K to 323.15 K and atmospheric pressure. Densities were obtained by using a vibrating-tube densimeter. Viscosities were determined by an automatic microviscometer based on the rolling ball principle. The excess molar volumes () and viscosity deviations (Δη) of the ternary system were derived from the experimental data and then were fitted to Clibuka, Nagata–Tamura and Redlich–Kister equation, respectively. The binary subsystems were correlated by Redlich–Kister equation. The values of and Δη were used to discuss the nature of mixing behaviours between mixture components.
