【摘要】 <正> 对复杂混合物中未知组分的定性鉴定是气相色谱(GC)分析的艰巨而重要的任务。GC定性方法很多,其中用Kovats指数值(I_R)定性,提高了定性数据的准确度。近年来很多色谱工作者把化合物的I_R与其物理性质、分子结构进行关联,对预测化合物I_R值提供了方便。我们在研究有机氮化合物的金属络合物新反应中,测更多还原

【Abstract】 Kovats retention indices of 36 compounds of alkylquinolines,alkylisoquinolines,phenylalkyl and phenoxylalkyl pyridines on Versamide 900 and SE-30 phases were determined.The retention indices of these compounds have been correlated with their molecular structure and physical properties,such as,boiling point,number of carbon atom in molecule,molecular weight,refractive index and molecula’r connectivity index.更多还原
