ABSTRACT

The densities and viscosities of aqueous solutions of piperazine (PZ) and aqueous blends of 2-amino-2-methyl- 1-propanol (AMP) and piperazine have been measured at (298, 303, 308, 313, 318, 323, 328, and 333) K. The experiments covered the concentration range of (0.2 to 0.8) molaL-1 piperazine (mass fraction piperazine (1.74 to 6.88) %) for the (PZ + water) system and mass fraction of (2 to 8) % for piperazine-activated blended AMP solutions. The results are compared with the available data in the literature. The experimental density and viscosity data were correlated as a function of temperature and concentration of amine.
