Thermophysical Analysis of Aqueous Solutions of Piperazine (PZ) and 2-Amino-2-hydroxymethyl-1, 3-propanediol + Piperazine (PZ + AHPD)

Physical properties such as density, viscosity, and surface tension of aqueous solutions of Piperazine (PZ) with mass fractions (100 w= 6.88, 13.76) were measured. All these properties were also measured for aqueous blends of 2-amino-2-hydroxymethyl-1,3- propanediol with Piperazine (AHPD + PZ) with mass fractions { 100 (w1/w2) = (1/6.88, 1/13.76, 7/6.88, 7/13.76, 13/6.88, 13/13.76 and 19/6.88, 19/13.76) }. These properties were investigated over the temperature range of 298.15 K to 333.15 K and were corr elated as a function of temperature. There was a decrease in all measured properties with increasing temperature.
