4,5-二氯-2-硝基苯胺及其醚化物的溶解度测定和关联

Measurement and Correlation of Solubilities of 4,5-dichloro-2-nitrobenzenamine and Etherate

测定了4,5-二氯-2-硝基苯胺和醚化物在二甲苯和甲苯中的溶解度。实验结果表明硝基苯胺和醚化物在二甲苯和甲苯中的溶解度均随温度的升高而增加。硝基苯胺在二甲苯中的溶解度要大于甲苯中的溶解度,而醚化物在两种溶剂中的溶解度相当。与二元体系相比,硝基苯胺在三元体系的溶解度增加,但醚化物的溶解度未发生变化。对硝基苯胺、醚化物的溶解度数据进行关联,计算值和实验值符合良好。

Solubilities of 4,5 -dichloro -2 -nitrobenzenamine and etherate were experimentally determined. The results showed that solubility of nitrobenzenamine and etherate increased with temperature increasing. Solubility of nitrobenzenamine in xylene was higher than that in toluene, but solubility of cthcrate was nearly the same in the two solvents. Solubility of nitrobenzenamine in ternary system was higher than that in binary system, but the solubility of etherate did not change. The solubilities of nitro- bensenamine and etherate in toluene or xylene were correlated with binary - parameters equation. The solubility of their mixture, which was a ternary system, was a correlated with ternary - paremeters equation. The calculated results fitted well with the experimental results. It showed that the equations can be used to correlate the solid - liquid equilibrium data of said systems.
