A New Method to Investigate the Clustering Phenomena in Supercritical Fluids
摘要:
The solvatochromic behavior of acetone in supercritical CO2 was investigated from 75 bar to 239 bar and at 318.15K. A clustering model is proposed to investigate the formation of solute-solvent and solute-solute clusters, based on the solvatochromic study and some reasonable assumptions. At lower pressures, there were more than one solute molecules in one cluster. At higher pressures, however, each cluster only contained one solute and the clustering of solute-solvent was dominant.
