Solubility of Tris(hydroxymethyl)aminomethane in Water + 1-Propanol Mixtures at Various Temperatures

Abstract

Solubility of tris(hydroxymethyl)aminomethane (TRIS) in various mass fraction compositions of water + 1-propanol solvent mixtures at (293.2, 298.2, 303.2, 308.2, and 313.2) K was measured using a laser monitoring technique. The generated data were mathematically represented using the Jouyban–Acree model. The correlated mole fraction solubilities are in good agreement with the corresponding experimental values as documented by an overall mean percentage deviation of 2.3 %. Densities of TRIS saturated solutions in water and 1-propanol at various temperatures were measured and employed to predict the density of TRIS saturated solutions in their binary solvent mixtures using a well-established method.
