Wang, Chen; Wang, Yongli; Yin, Qiuxiang; Xu, Zhao; Bao, Ying; Hou, Baohong; Liu, Wei; Hao, Hongxun published the artcile< Solubilities of 3-Chlorophthalic Anhydride and 4-Chlorophthalic Anhydride in Different Pure Solvents>, Name: 5-Chloroisobenzofuran-1,3-dione, the main research area is solubility chlorophthalic anhydride pure solvent.
To help the development of separation technol. for the mixture of 3-chlorophthalic anhydride and 4-chlorophthalic anhydride, the solubility data of 3-chlorophthalic anhydride and 4-chlorophthalic anhydride in tert-amyl alc., carbon tetrachloride, cyclohexane, methanol, Me acetate, and acetonitrile were measured at of 283.15 K to 328.15 K by a static method. The solubilities of both 3-chlorophthalic anhydride and 4-chlorophthalic anhydride increased with the increase of temperature The exptl. solubility data in six pure solvents were correlated by the modified Apelblat equation, the van’t Hoff equation, the λh (Buchowski) equation, and the NRTL model, among which the modified Apelblat equation can give better correlation results than other models. In addition, the dissolution thermodn. properties, including enthalpy, entropy, and Gibbs energy were determined The exptl. data would be of great significance for the design and optimization of the crystallization processes of 3-chlorophthalic anhydride and 4-chlorophthalic anhydride.
Journal of Chemical & Engineering Data published new progress about Entropy (of solution). 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Name: 5-Chloroisobenzofuran-1,3-dione.
