本文简要介绍了超临界流体的基本概念和性质,评述了化学热力学在超临界萃取、超临界态化学反应、超临界流体制备材料等方面的作用和研究进展,讨论了二氧化碳-离子液体两相体系的热力学行为。
The concept and characteristics of supercritical fluids are briefly introduced. The chemical thermodynamics related with supercritical fluid extraction, the chemical reactions in supercritical fluids, and material processing using supercritical fluids are reviewed. Thermodynamics of carbon dioxide/ionic liquid biphasic systems are also discussed.
