The solubility of dimethyl succinylsuccinate in (methanol + water) solvent mixtures was measured from (283.75 to 327.25) K.
The solubility of dimethyl succinylsuccinate in (methanol + dimethyl succinate) solvent mixtures was measured.
The melting point and the fusion enthalpy of dimethyl succinylsuccinate were measured by DSC.
The Wilson and the NRTL models provide good accuracies in correlating the SLE of the systems, respectively.
A suggestion is provided to improve the dimethyl succinylsuccinate process.
