Measurement and correlation for the solubility of dimethyl succinylsuccinate in (methanol + water) and (methanol + dimethyl succinate) binary solvent mixtures
In order to improve the process of dimethyl succinylsuccinate production, the solubility data of dimethyl succinylsuccinate in the binary solvent mixtures consisting of (methanol + water) and(methanol + dimethyl succinate) were measured within the temperature range of (283.75 to 327.45) K by a dynamic method. The solubility of dimethyl succinylsuccinate in both of the selected solvent mixtures increase with temperature, and the solvent mixtures (methanol + dimethyl succinate) have much more dissolving capacity for DMSS solute. The experimental data were well-correlated with the Wilson model and the NRTL model, and the root-mean-square deviations for the Wilson and the NRTL models ranged from (0.20 to 0.94) K and (0.18 to 0.93) K, respectively. The melting point and the fusion enthalpy of dimethyl succinylsuccinate were detected by differential scanning calorimetry (DSC). The improvement of dimethyl succinate process was suggested according to the determined data.
