在278.15 ~ 333.15 K的常压下,用重量法测定了n-氯丁二酰亚胺在纯正丁醇、乙酸乙酯、丙酮、异丙醇、四氢呋喃、乙腈和乙酸酐中的溶解度。n -氯丁二酰亚胺在所选溶剂中的溶解度随温度升高而升高。将溶解度数据与修正的Apelblat方程和van 't Hoff方程进行关联,得到模型参数。实验结果可为工业上n -氯丁二酰亚胺的提纯工艺优化提供参考。异丙醇可作为n -氯丁二酰亚胺结晶的优良溶剂。
Solubility data were measured for N-chloro succinimide in pure n-butanol, ethyl acetate, acetone, isopropanol, tetrahydrofuran, acetonitrile and acetic anhydride at the temperature range between 278.15 K and 333.15 K under atmospheric pressure by gravimetric method. The solubility of N-chloro succinimide in those selected solvents increased with increasing temperature. The solubility data were correlated with the modified Apelblat equation and the van’t Hoff equation to obtain the model parameters. The experimental results could be useful for optimizing the process of purification of N-chloro succinimide in industry. Isopropanol could be the excellent solvent in the crystallization of N-chloro succinimide.
