The Study Of Quantitative Describing Of Chromatographic Retention Value By Means Of Molecular Recognition Principle

One important theoretic problem in chromatographic analysis is to research into the movement of separated matters in chromatographic column, in other words, to explore how the component is to be recognized one by one and separated effectively in the column. Because many physical properties of substances are related closely with the intermolecular forces, in fact, the chromatographic separating process is also that of molecular recognition, which the impulsion is the various intermolecular forces, including the selective intermolecular force (SIF).Summarizing the experience themselves and many reports about physical chemistry and catalytic principle, Professor JIN songshou and Professor ZHENG Xiaoming proposed the theory of Adaptability of Group Structure (AGS), and then the concept of Selective Intermolecular Force (SIF). It is the Selective Intermolecular Force that, they pointed, is the internal cause and motive force of"molecular recognition"in the forming process of supramolecules, so it is necessary to describe quantitatively the special force. Since that we determined is the macro-incarnation of interreaction among molecules, including orientation force, induction force, and dispersion force, and it is difficult to strip the interreaction nowadays, some methods and techniques must be introduced into our research to take the quantitative description of interreaction among molecules. In this work, we hope to set up the"bridge"to combine the inner structure of molecules with their macroscopic physical-chemical propertices by means of the chromatographic research, then to make some quantitative description for the interreaction among molecules in a certain extent, and to make the direct and entire quantitative description in the future.This work was divided into 5 chapters.After summarizing the 217 referenced literatures, in the first chapter, we discussed the relationship between the selective molecular force and supramolecular chemistry, the varied methods of describing the molecular recognition process, and the methods to quantitatively conjugate the connection of molecular structure and its properties. On the base, we proposed the essence consider about the work.
