Making use of the modified supercritical fluid chromatograph,we measured the infinite dilution diffusion coefficients of benzene and acetone in supercritical carbon dioxide under different temperatures and pressures,and further develop an opening experiment in order to reinforce students' understanding of the supercritical fluid and properties.The depth and breadth of students' perspective will be developed.Their experimental skills will be enhanced on the basis of learning operational principle,instrumental structure,application and manipulating method of supercritical liquid chromatograph,which is beneficial to cultivate the high quality chemistry talent.
- Supercritical liquid,
- Carbon dioxide,
