摘要
A database of partition constants for more than 300 compounds of industrial, environmental and biological interest in nineteen totally organic biphasic systems is reported. The biphasic systems, consist of the polar organic solvents acetonitrile, methanol, N,N-dimethylformamide, dimethyl sulfoxide, formamide, propylene carbonate, ethylene glycol, ethanolamine and 3,3,3-trifluoroethanol with n-heptane or n-hexane (10 systems), isopentyl ether (5 systems), 1,2-dichloroethane (2 systems) and 1-octanol (2 systems) of suitable low mutual solubility. The solvation parameter model is used to identify compounds with extreme partition constant values and to develop a selection guide based on the cluster analysis of the model system constants to identify biphasic systems for liquid-liquid extraction.
