Abstract
The present work concerns with an investigation on the solubility of cis,cis-muconic
acid dissolution in different polar solvents by characterizing and modeling the dissolution
as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated
as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of
cis,cis-muconic acid solubility data, the molar fraction and temperature were correlated using
the modified Apelblat equation model, which is applied for the mathematic fitting of experimental data.
A total relative average deviation of 3.54% was obtained for the experimental results and
the solubility data obtained with the model, thus attesting the adequacy for this study. The use
of modified Apelblat equation also allowed to determine the molar enthalpy and molar entropy
of dissolution. The dissolution of cis,cis-muconic acid in water, ethanol, 2-propanol and acetic acid,
over temperatures ranging from 298.15 to 348.15 K, has been shown to be exothermic.
