Relations entre solute, solvant et adsorbant en chromatographie sur couches minces : III. Relation entre la structure moléculaire du solvant et la migration du soluté sur l'adsorbant application à la chromatographie des organophosphorés neutres

Abstract

Relationships between the solute, solvent and adsorbent in thin-layer chromatography. III. Relationship between the molecular structure of the solvent and the migration of solute on the layer. Application to the chromatography of neutral organophosphorus compounds In view of the fact that solvents can be either hydrogen-bond acceptors or hydrogen-bond donors, some simple chromatographic processes may be schematized. This possibility has been utilized in the chromatography of organophosphorus compounds on silica gel using various solvent systems. The information obtained on solute-solvent, adsorbent-solvent and adsorbent-solute interactions has opened the way for a rapid choice of the most suitable adsorbent and solvent in a given case.
