| 摘 要： | 首次研究并制作出2，4-二硝基甲苯、2，6-二硝基甲苯与乙醇或硫酸的二固-液三组分体系在不同温度下的相图。由相图得出，为析出尽量多的2，6-DNT，以乙醇作溶剂时温度高些有利，而以硫酸作溶剂时，温度低些有利。

| Abstract: | Phase diagram of a tertiary mixture composed of two solid components (2,4-DNT and 2,6-DNT) and one liquid component(ethanol or sulphuric acid) was first set up by solubility approach. The solubility of both 2,4-DNT and 2,6-DNT in ethanol or sulphuric acid,and the cocrystallizing point of the tertiary mixture were determined. From the experimental results,it is concluded that in order to precipatate more 2,6-DNT,the crystallization process should be carried out at higher temperature for solvent of ethanol,but at lower temperature for solvent of sulphuric acid. |
