超临界流体特性及在有机溶剂中相行为研究

摘要

Supercritical fluid had many unique properties,such as viscosity,density,diffusion,coefficient,etc.were very sensitive with temperature and pressure changes.Through the experiment of effect between supercritical carbon dioxide and fluorine atoms examine fluorine atoms to the effects of inflation,and the effect between supercritical carbon dioxide and carbonyl,carbonyl effects to inflation was examined,thus the best solvents were determined and a series of inflation experiments with cinnamaldehyde were carried out.%超临界流体具有许多独特的性质,如粘度、密度、扩散系数、溶剂化能力等性质随温度和压力变化十分敏感：粘度和扩散系数接近气体,而密度和溶剂化能力接近液体。本文通过实验首先进行了超临界二氧化碳与氟原子作用考察氟原子的引入对膨胀效果的影响、超临界二氧化碳与羰基作用,考察羰基对膨胀效果的影响、从而确定出最佳的共溶剂[1]。随后,使之与肉桂醛做一系列比例的膨胀对比实验。
