【摘要】 本文以烷基吡啶为例,研究了芳环异构体的保留指数与分子结构及极性固定液间的关系。本工作主要研究了所列各类型烷基吡啶在多种状态极性溶剂系统中,专门表现出来的特殊相互作用力,测定了它们的保留指数,实现了对工业烷基吡啶混合物的选择性分离和分析。通过本文工作得出了芳环取代基位置不同,性质不同时,在不同极性固定液中保留值的规性。更多还原

【Abstract】 In this Paper, The relationship between setention index of aromatie isomeride and the moleculer construction and polar slationary liguid is studied with alkyl pyridine for example. More attention has been paid in studying the sperfic mteract forces between alkyl pyridine and Various polar so lent The selectiye separation and analysis of the mixtures of industrial alkyl pyridine, were realized, the retention index was detected. In this paper the regularity of retention values of the aromatic compounds with -diffrent position groups and diffiend quality to diffrent polar sovent was fonnd by our working更多还原
