摘要

作者分析了喹啉、1,2,3,4-四氢喹啉和哒嗪并[4,5-c]喹啉衍生物在十八烷基硅胶反相高效液相色谱条件下的保留温度相关性。计算了这些化合物的吸附热力学特性。发现吸附焓的变化取决于水-乙腈洗脱液中乙腈的含量。

Thermodynamics of the Sorption of Quinoline Derivatives, 1,2,3,4-Tetrahydroquinoline and Pyridazino[4,5-c]Quinoline Under Conditions of RP HPLC

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.
