摘要：

The solubility of succinic anhydride in pure solvents and binary {gamma-butyrolactone (GBL) + tetrahydrofuran (THF)} mixtures was determined at a limited temperature range of (283.15-323.15) K by using a gas chromatography method. The experimental results revealed two aspects. On the one hand, the solubility of succinic anhydride increased monotonically with rising temperature in binary (gamma-butyrolactone + tetrahydrofuran) mixtures when solvent composition remains constant. On the other hand, the solubility of succinic anhydride decreased monotonically with the increasing tetrahydrofuran content when temperature remains constant. The modified Apelblat equation, lambda h equation, CNIBS/R-K equation and Jouyban-Acree equation were successfully used to correlate the experimental solubility in diverse solution systems. Furthermore, the mixing thermodynamic properties of succinic anhydride in binary solvent mixtures were calculated and discussed. The results indicate that the mixing process of succinic anhydride in the investigated solvents is spontaneous. (C) 2016 Elsevier Ltd.
