The solubility of tris(hydroxymethyl)aminomethane (TRIS) in various mass fractions of ternary solvent mixtures of water + methanol +1-propanol at 293.2 K, 298.2 K, 303.2 K, 308.2 K, and 313.2 K was measured using a laser monitoring technique. The mole fractions of water in the ternary mixtures were between 0.90 and 0.17; the mole fraction solubility of TRIS ranged between 0.0150 and 0.1187. The generated data was mathematically represented by the combined models of Jouyban-Acree and van't Hoff, enabling the solubility to be expressed as a function of both ternary solvent compositions and temperatures. The back-calculated mole fraction solubilities agreed with the corresponding experimental values by an overall mean percentage deviation of 5.6%. © 2015 American Chemical Society.

The solubility of tris(hydroxymethyl)aminomethane (TRIS) in various mass fractions of water + methanol 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 back-calculated mole fraction solubilities are in good agreement with the corresponding experimental values as documented by an overall mean percentage deviation of 3.2 %. © 2014 American Chemical Society.

Solubility of tris(hydroxymethyl)aminomethane (TRIS) in various mass fractions of binary solvent mixtures of methanol and 1-propanol [at (293.2, 298.2, 303.2, 308.2, and 313.2) K] was measured and mathematically represented using the Jouyban-Acree model. The correlated mole fraction solubilities are in good agreement with the corresponding experimental values with an overall mean percentage deviation of 1.7%. Densities of saturated solutions of TRIS in pure methanol and 1-propanol at various temperatures were measured and employed to predict the density of saturated solutions of TRIS in their binary solvent mixtures.

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. © 2014 American Chemical Society.
