ABSTRACT

The densities and viscosities of aqueous blends of 2-piperidineethanol (2-PE) with piperazine (PZ) at (288, 293, 298, 303, 308, 313, 318, 323, 328, and 333) K as well as the surface tension of aqueous blends of PZ with N-methyldiethanolamine, 2-amino-2-methyl-1-propanol, and 2-PE at (293, 298, 303, 308, 313, 318, and 323) K have been measured. 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 ternary mixtures are presented as a function of temperature and amine concentration.
