摘要
在温度343.15~383.15 K、压力14~22 MPa条件下,采用动态法测定分散紫27、分散蓝72在超临界CO_(2)中的溶解度。并采用Chrastil半经验模型和AdMST半经验方程对实验结果进行关联,探讨影响分散染料在超临界CO_(2)中溶解度的因素。结果表明:分散紫27在超临界CO_(2)中的溶解度为2.69×10^(-6)~7.35×10^(-6) mol/mol,压力越高,CO_(2)密度越大,分散紫27在超临界CO_(2)中的溶解度越高;随着温度的升高,分散紫27的溶解度先升高后降低;分散蓝72在超临界CO_(2)中的溶解度为7.17×10^(-6)~13.38×10^(-6) mol/mol,且随着温度的升高而升高,随着压力的升高而升高。
The solubility of disperse violet 27 and disperse blue 72 in supercritical CO_(2) was determined by dynamic method under the conditions of 343.15~383.15 K and 14~22 MPa.The Chrastil semi-empirical model and the Ad MST semi-empirical equation were used to correlate the experimental results,and the factors af⁃fecting the solubility of disperse dyes in supercritical CO_(2) were discussed.The results showed that the solubili⁃ty of disperse violet 27 in supercritical CO_(2) was 2.69×10^(-6)~7.35×10^(-6) mol/mol,the higher the pressure,the higher the carbon dioxide density,and the higher the solubility of disperse violet 27 in supercritical CO_(2).As the temperature increased,the solubility of disperse violet 27 increased first and then decreased.The solubili⁃ty of disperse blue 72 in supercritical CO_(2) was 7.17×10^(-6)~13.38×10^(-6) mol/mol,and increased with the increase of temperature and pressure.
