2-氯-4,6-二硝基间苯二酚在乙醇/水混合溶剂中溶解度的研究

Study on the 2-Chloro-4,6-dinitroresorcinol Solubility in Ethanol/Water Mixtures

利用紫外吸收方法测得了2-氯-4,6-二硝基间苯二酚在乙醇/水混合溶剂中的溶解度,将实验溶解度数据和三参数经验模型相关联,通过系统的研究,证明三参数经验模型是合理的数学方程,可以准确地描述在乙醇/水混合溶剂中2-氯-4,6-二硝基间苯二酚溶解度变化规律,模型三参数(a,b和c)被确定。2-氯-4,6-二硝基间苯二酚在乙醇/水混合溶剂中的溶解度随温度的升高而增大;随水含量的升高而减小。

The solubility of 2-chloro-4,6-dinitroresorcinol in ethanol/water mixtures was measured using ultraviolet absorption method. The solu- bility data were correlated with a semiempirical equation. Through the systemic study, the semiempirical equation was found to be a reasonable mathe- matical representation to fit the experimental data, and the parameters （a, b and c） were obtained. The 2-chloro-4,6-dinitroresorcinol solubility in ethanol/water mixtures increased with rising temperature and decreased with increasing the water content.
