Density and viscosity measurements were performed on binary liquid mixtures of diethylamine and 2-propanol, 2-butanol and 2-pentanol at temperatures (293.15 to 323.15) K and ambient pressure. Using these experimental data, excess molar volumes VE m, and viscosity deviations Dg, have been calculated. Results were analyzed to gain insight about liquid mixture interactions. Also the friction theory founded on the PC-SAFT model was used to calculate the viscosities of binary mixtures. The model, which links viscosity to the repulsive and attractive pressure terms of the PC-SAFT model, performs very well in all cases, with a global average absolute deviation of 3% and shows predictive capabilities for heavier compounds
