通过实验并使用 COSMO-RS 模型进行先验预测,研究了对羟基苯甲酸烷基酯和布洛芬在非离子和离子表面活性剂水溶液中的分配。检查了有机 (Bu 4 NBr) 和无机 (NaCl) 电解质的影响。添加 NaCl 会导致辛基酚聚乙二醇醚溶液中对羟基苯甲酸酯的分配系数略有增加,而十二烷基硫酸钠 (SDS) 系统中的分配系数则更为显着。向 SDS 水溶液中添加 NaCl 时,布洛芬的分配系数增加;如果向十二烷基三甲基溴化铵 (DTAB) 溶液中添加 Bu 4 NBr,则布洛芬的分配系数降低。实验数据与计算数据之间的良好一致性表明 COSMO-RS 在预测电解质存在下的胶束/水分配系数方面具有很高的潜力,并使其成为药物和药物载体设计以及优化胶束反应或胶束增强分离过程的宝贵工具。
The partitioning of alkyl parabens and ibuprofen in aqueous solutions of nonionic and ionic surfactants is studied experimentally and via a priori predictions using the COSMO-RS model. The effects of organic (Bu 4 NBr) and inorganic (NaCl) electrolytes are examined. Addition of NaCl results in a slight increase in the partition coefficients of parabens in solutions of octylphenolpoly(ethyleneglycolether) and a more pronounced increase in the sodium dodecyl sulfate (SDS) system. The partition coefficients of ibuprofen increase on addition of NaCl to aqueous solutions of SDS and decrease if Bu 4 NBr is added to dodecyl trimethyl ammonium bromide (DTAB) solutions. Good agreement between experimental and calculated data shows a high potential of COSMO-RS in the prediction of micelle/water partition coefficients in the presence of electrolytes and makes it a valuable tool in drug and drug-carrier design as well as in optimizing micellar reactions or micelle-enhanced separation processes.
