摘要
拓扑指数ｘｚ和路径数Ｐ１、Ｐ３、Ｐ４是表征烷烃分子大小、支化度和形状等结构特征的重要参量．据此，本文将ｘｚ、Ｐ１、Ｐ３、Ｐ４作为独立参量，用多元线性模型系统地研究了烷烃结构－性质的定量关系，预测了含２～９个碳原子烷烃的原子化焓、标准生成焓、汽化焓、摩尔体积、摩尔折射度、正常沸点、密度、溶解度等１０项物理化学性质．计算方法简单，结构意义明确。
The topological index x z numbers of path 1,3,4 (P 1,P 3,P 4) can be used to characterize the size,branchins and shape of alkanes.With this,we can take x z,P 1、P 3、P 4 for separate parameters to predict ten physichemical properties.including heat of atomization,heat of formation,heat of vaporation,molar volume,molar refraction,normal boiling point,density,solubility and others for alkanes.It has been demonstrated that the method possesses the advantage of easy computation and clear structural significance.The results are also satisfactory.
