Comparison of Partition Chromatographic Parameters of Lipophilic Organic Electrolytes for Solvents of Various Donor-Acceptor Properties. VII. Discussion of the Correlation Method from the Viewpoint of the Additivity Principle

Abstract

A graphical correlation method proposed by Rohrschneider and Littlewood for gas chromatography is applied to liquid-liquid partition of five homologous series of organic bases. The experimental data are interpreted in terms of the additivity of R_M values. Graphical estimation of partition coefficients of more complex molecules from group δR_Ms values and the correlation line of a simpler solute is described.
