Thermodynamics of the Sorption of Quinoline Derivatives, 1,2,3,4-Tetrahydroquinoline and Pyridazino[4,5-c]Quinoline Under Conditions of RP HPLC
摘要
Abstract
The authors analyze temperature dependences of the retention of derivatives of quinoline, 1,2,3,4-tetrahydroquinoline, and pyridazino[4,5-c]quinoline under conditions of reversed-phase high-performance liquid chromatography on octadecyl silica gel. The thermodynamic characteristics of sorption of these compounds are calculated. The change in the enthalpies of sorption are found to depend on the content of acetonitrile in the water–acetonitrile eluent.
