Density and viscosity of ternary mixture of {1-amino-2-propanol + 2-methyl-1-propanol + 1-propanol} in the temperature range of (293.15–333.15) K at atmospheric pressure

Abstract

In the present work, the density, ρ, and viscosity, η, of ternary mixture of {x11-amino-2-propanol + x22-methyl-1-propanol + x31-propanol} were measured over the entire composition range at temperatures (293.15–333.15) K and ambient pressure (p = 0.1 MPa). The density values were obtained using an Anton Paar DMA 4500 M instrument. The excess molar volumes, VmE, and viscosity deviations, Δη, were calculated from the measured values of density and viscosity. The excess molar volumes of ternary mixture are negative over the entire mole fraction range and become more negative with increasing temperature. Viscosity deviations for the ternary mixture are negative over the entire mole fraction range and decrease with increasing temperature. The Cibulka equation was used to correlate the ternary excess molar volumes and viscosity deviations.
