Equilibrium Solubility of Sodium 2,4-Diaminobenzenesulfonate in Binary NaCl + H₂O, Na₂SO₄ + H₂O, and C₂H₅OH + H₂O Solvent Mixtures at Elevated Temperatures from 273.15 K to 323.15 K

Abstract

The solubility of sodium 2,4-diaminobenzenesulfonate in binary NaCl + H 2 O, Na 2 SO 4 + H 2 O, and C 2 H 5 OH + H 2 O solvent mixtures were measured at elevated temperatures from 273.15 K to 323.15 K by a steady-state method. The results of these data were correlated by a modified Apelblat equation.

Determination and correlation of solubility and dissolution thermodynamics of m‐toluic acid and isophthalic acid in binary (water plus ethanoic acid) solvent mixtures

“…The solubility data of m‐TA, as well as IPA in different mixtures of ethanoic acid + water were measured by the steady‐state method, a frequently used method for solubility determination . Before each experiment, solvent and excess solute were weighed and then put into the jacketed vessel.…”

“…In this work, the solubility data of m‐TA at temperatures of 313.2 to 383.2 K, as well as IPA at temperatures of 373.2 to 463.2 K in ethanoic acid and water and their mixtures were measured using the steady‐state method, which has been demonstrated to bereliable in determining solubility data . Although the experimental temperatures of m‐TA are less than 384 K, since the solid m‐TA would turn into liquid above its melting point of 384 K, the solubility data can be useful in subsequent processes following IPA production, such as the treatment of wastewater or liquid waste containing m‐TA and other applications.…”

“…In the study, three equations, i.e. the ideal solution equation (eq ), the Apelblat equation (eq ), and the λ– h equation (eq ), were used to correlate the experimental data. − In the equations, x represents the solubility in mole fraction, T is temperature in kelvin (K), and T m is the melting point in kelvin, A ′, B ′, A , B , C , λ, and h are all substance-specific parameters.…”
