表面活性剂在超临界二氧化碳中的应用
pplication of surfactants in supercritical carbon dioxide
作为对环境友好的常规有机溶剂的替代品,液态或超临界态二氧化碳受到了广泛的关注。然而,由于在超临界二氧化碳中较低的溶解性,限定的超临界二氧化碳作为溶剂的应用范围,尤其是对于极性化合物更是如此。这些溶解性问题可以通过利用特殊的表面活性剂形成胶束或者二氧化碳包水型微乳液来解决。这样便扩大了液态或者超临界态二氧化碳作为溶剂的应用范围。
Liquid or supercritical carbon dioxide (sc-CO2) has attracted much interest as environmentally benign alternative for conventional organic solvents. However, low solubility in carbon dioxide, especially polar compounds, is a limitation to the wide practical application of sc-CO2. These solubility problems have been overcome by employing some specialised CO2-soluble surfactants to form reverse micelles or water-in-CO2 (w/c) microemulsions, which could accelerate the development of a broad range of CO2-based processes.
