This study describes the enhancement in the solubility and controlled-release of fragrance agents (menthol, four n-alkanols, and three aromatic esters) using three CO2 switchable surfactants (N-alkylimidazolium bicarbonates). The surfactants significantly improved the solubility of fragrance agents in water. N-Dodecylimidazolium bicarbonate was the most effective surfactant to solubilize menthol. A stability test indicated that the surfactant could stably disperse menthol in water. Moreover, the surfactants improved the solubility of n-alkanols to different levels, however, the solubility of the aromatic esters equally. The release of menthol from the surfactant solution under N2 at different durations of bubbling time, temperatures, and flow velocities were studied.

CO2 可转换表面活性剂水溶液中芳香剂的增溶和释放

本研究描述了使用三种 CO 2可转换表面活性剂(N-烷基咪唑碳酸氢盐)增强香料(薄荷醇、四种链烷醇和三种芳族酯)的溶解度和控释。表面活性剂显着提高了香料在水中的溶解度。N-十二烷基咪唑鎓碳酸氢盐是增溶薄荷醇最有效的表面活性剂。稳定性测试表明,该表面活性剂可以稳定地将薄荷醇分散在水中。此外,表面活性剂将正链烷醇的溶解度提高到不同程度,而芳族酯的溶解度相同。N 2下表面活性剂溶液中薄荷醇的释放在不同的起泡时间、温度和流速进行了研究。
