ABSTRACT

The densities and viscosities of aqueous solutions of 2-piperidineethanol (2-PE) and aqueous blends of 2-piperidineethanol with monoethanolamine (MEA) and diethanolamine (DEA) have been measured at (288, 293, 298, 303, 308, 313, 318, 323, 328, and 333) K. The total amine mass fraction in all solutions was kept within 30 % in view of recent interest in using concentrated amine solutions in gas treating. Correlations for the density and viscosity of the binary and the ternary mixtures are presented.
