摘要
为获得最佳的溶解度试验数据并得到溶解度与工艺测量条件之间的关系,探究分散染料在超临界CO_(2)流体中的溶解规律。在温度343.15~393.15 K、压力10~22 MPa的条件下,使用超临界流体试验装置测量分散橙25在超临界CO_(2)流体中的溶解度,并对染料的溶解性进行分析。利用Kumar-Johnston(K-J)、Sung-Shim(SS)和Mendez-Santiago-Teja(MST)等3种半经验模型对染料的溶解度进行拟合。结果表明:染料的溶解度随压力和温度的升高而增加;K-J、SS和MST模型的平均相对偏差分别为7.55%、8.20%和11.92%,其中K-J模型拟合下的试验值和计算值的相关性最高,关联效果优于其他两种半经验模型。
To obtain the best solubility experimental data and the relationship between solubility and measurement conditions,the solubility of disperse dyes in supercritical CO_(2)fluid was investigated.The solubility of disperse orange 25 in supercritical CO_(2)fluid was measured using a supercritical fluid test apparatus under the conditions of temperature 343.15 K to 393.15 K and pressure 10 MPa to 22 MPa,and the solubility of the dye was analyzed.Three semi-empirical models,Kumar-Johnston(K-J),Sung-Shim(SS)and Mendez-Santiago-Teja(MST),were used to fit the solubility of the dye.The results show that the solubility increases with the increase of pressure and temperature;the average absolute relative deviation of the three models of K-J,SS and MST is 7.55%,8.20%and 11.92%,respectively.The correlation between experimental values and calculated values under K-J model is the highest,and the correlation effect is better than that of the other two semi-empirical models.
