二元交互作用参数cij什么时候取0.2，什么时候取0.3? 1. aji = 0.20 for hydrocarbons and polar, nonassociated species (e.g., n-heptane/acetone). 2. aji = 0.30 for nonpolar compounds (e.g., benzene/ n-heptane), except fluorocarbons and paraffins; nonpolar and polar, nonassociated species (e.g., benzene/acetone); polar species that exhibit negative deviations from raoult’s law (e.g.,acetone/chloroform) and moderate positive deviations (e.g., ethanol/water); mixtures of water and polar nonassociated species (e.g., water/acetone). 3. aji = 0.40 for saturated hydrocarbons and homolog perfluorocarbons (e.g., n-hexane/perfluoro-n-hexane). 4. aji = 0.47 for alcohols or other strongly self-associated species with nonpolar species (e.g., ethanol/benzene);carbon tetrachloride with either acetonitrile or nitromethane; water with either butyl glycol or pyridine. 下面两篇是最原始的文献记载。 renon, h., and j.m. prausnitz, aiche j., 14, 135–144 (1968). http:///doi/10.1002/aic.690140124/abstract renon, h., and j.m. prausnitz, ind. eng. chem. process des. dev., 8,413–419 (1969). 查看更多
