![عکس صفحه اول مقاله: Solubilities of succinimide in different pure solvents and binary methanol + ethyl acetate solvent mixtures Solubilities of succinimide in different pure solvents and binary methanol + ethyl acetate solvent mixtures](/preview/png/674148.png)
Solubility data were measured for succinimide in pure ethyl acetate, acetonitrile, ethanol, acetone, tetrahydrofuran, methanol, isopropanol, n-butanol and binary methanol + ethyl acetate solvent mixtures at the temperature range between 278.2 K and 325.1 K under atmospheric pressure by gravimetric method. The solubilities of succinimide in those selected solvents increased with increasing temperature. The solubility data were correlated with the modified Apelblat equation and λh equation to obtain the model parameters. The experimental results could be useful for optimizing the process of purification of succinimide in industry. Methanol could be the excellent solvent in the crystallization of succinimide.
► We measure the solubility of succinimide in diverse solvents between 278.2 and 325.1.
► The modified Apelblat equation is used to correlate the experimental data.
► Interactions may affect the solubility of succinimide are discussed.
► We consider methanol as an excellent solvent for purification of succinimide.
