摘　　要：为实现超临界二氧化碳(CO2)染色的工业化应用,采用自主研发的高压超临界流体实验装置,在温度为353.15~393.15K、压力为16~24MPa条件下,利用动态法测量了分散红11(1,4-二氨基-2-甲氧基蒽醌)在超临界二氧化碳中的溶解度,并采用Chrastil经验模型和MST方程对实验结果进行拟合,探讨影响分散染料在超临界CO2中溶解度的因素。结果表明:压力越高,二氧化碳密度越大,分散红11在超临界CO2中的溶解度越高;随温度升高,分散红11的溶解度先增加后降低;分散红11的最优溶解度工艺条件为温度383.15K,压力24MPa;Chrastil经验模型关联水平在0.90以上,MST方程关联水平为0.55,Chrastil经验模型关联结果优于MST方程。In order to realize the industrial application of supercritical carbon dioxide (CO 2) dyeing, a high pressure supercritical fluid experimental device was developed independently under the conditions of temperature of 353.15-393.15 K and pressure of 16-24 MPa. The solubility of Disperse Red 11 (1,4-diamino-2-methoxyanthraquinone) in supercritical carbon dioxide was measured by a dynamic method. The experimental results were fitted by Chrastil empirical model and MST equation, and the factors affecting the solubility of disperse dyes in supercritical CO 2 were discussed. The results show that the higher the pressure is, the higher the density of carbon dioxide is, the higher the solubility of Disperse Red 11 in supercritical CO 2. With the increase of temperature, the solubility first increases and then decreases. The optimum process conditions of solubility of Disperse Red 11 is temperature of 383.15 K and pressure of 24 MPa. The correlation level of Chrastil empirical model is above 0.90, and the correlation level of MST equation is 0.55. Chrastil empirical model has better correlation results than MST equation.
