| 9 | A New Method to Investigate the Clustering Phenomena in Supercritical Fluids显示文摘The solvatochromic behavior of acetone in supercritical CO2 was investigated from 75bar to 239 bar and at 318. 15K. A clustering model is proposed to investigate the formation of sol-ute-solvent and solute-solute clusters, based on the solvatochromic study and some reasonableassumptions. At lower pressures, there were more than one solute molecules in one cluster. Athigher pressures, however, each cluster only contained one solute and the clustering of solute-solvent was dominant. | Lu, J Huo, Q Han, BX Yan, HK | 1998 | Chinese Chemical Letters1998，9，2： | 0 |
