ABSTRACT
Property characterization plays an important role in the design of process and operations. Correlating the physical and chemical properties with key process parameters such as temperature and composition leads to the understanding of the systems behaviour. Thus, in this work, properties including density, refractive index, and viscosity data of aqueous solutions of n-tris(hydroxymethyl)methyl-3-aminopropanesulfonic acid (TAPS) were measured at varied temperature and fixed pressure. The considered temperatures and pressure were from 293.15 to 343.15 K and at atmospheric pressure, respectively. The entire composition range where TAPS is still soluble in water were the studied compositional range. The experimental data were correlated using a modified form of the Vogel-Tamman-Fulcher equation leading to an Arrhenius-type asymptotic exponential function. In general, the data presented together with the proposed correlation were of sufficient accuracy with an overall AAD value of 0.27%. Excess properties were also computed to account for the deviations of the solution from ideality.
