Viscosities and Excess Properties of Aqueous Solutions of Mono- and Diethylethanolamines at Temperatures between 298.15 and 353.15 K

Viscosities of aqueous solutions of monoethylethanolamine and diethylethanolamine have been measured at temperatures from 298.15 to 353.15 K over the entire range of concentrations. The excess activation energies for viscous flow and the excess entropies for viscous flow have been calculated for these aqueous solutions in this temperature range. The viscosities, excess activation energies for viscous flow, and the excess entropies for viscous flow of these solutions have been compared with our earlier values for aqueous solutions of monoethanolamine.
