摘要
超临界CO2 具有气体的低粘度、高扩散系数和液体的高密度 ,且化学惰性 ,无毒无腐蚀 ,临界状态容易实现 ,是一种性能优良的环境友好溶剂。本文在超临界CO2 作为萃取剂、化学反应介质、取代传统工艺助剂和溶剂及用于分析测试等方面综述了其应用研究。
Supercritical carbon dioxide is an environmentally friendly solvent because of its prominent properties,such as gaslike lower viscosity and higher diffusion coefficient,liquidlike higher density,tunable solubility,easily accessible critical point,low cost,nontoxic,nonflammability,chemical and thermal stability,etc.This paper summarized some research applications of supercritical carbon dioxide such as extraction agent,reaction medium,replacement for organic solvents in traditional industry,used in analyzing and detection,and so on.
