Abstract The gravimetric method was utilized here for obtaining the solubility of trans‑Cinnamic (t‑CA) under atmospheric pressure (p = 101.1 kPa) in water, methanol, ethanol and aqueous binary mixed solvents from T = (288.15 15 to 328.15) K. The solubility of t‑CA was strongly affected by both the mass ratio of the solvents and experimental temperature. The mole division solubility of t‑CA was observed to be most in pure ethanol at 328.15 K and least in unadulterated water at 288.15 K. The experimental values were regressed by the Jouyban−Acree, van't Hoff−Jouyban−Acree, Apelblat−Jouyban−Acree and Ma models. The biggest estimation of root-mean-square deviation was 1.94 × 10−3 and 4.11 × 10−3 and the relative normal deviation was 4.06 × 10−2 and 5.58 × 10−2 for the binary (ethanol + water) and (methanol + water) mixtures, respectively. Moreover, the disintegration enthalpy and disintegration entropy of t-CA in the comparing blended solvents were anticipated. The results may supply a basic theoretical guidance for industry.
