摘    要:首次提出了一种基于元素和化学键的估算有机物正常沸点的新方法,在4060种有机物实验数据的基础上,回归出了7个正常沸点估算式和估算式的参数值。对4068种有机物的正常沸点进行了估算,其平均相对误差为3.63%,总体估算精度明显优于相比较的基团贡献法,对炔烃、氯衍生物、碘衍生物,尤其是对烷烃类、溴衍生物、芳烃、脂环烃和含硫化合物的估算误差明显减小。

关 键 词:正常沸点  估算方法  元素  化学键  基团贡献法

Abstract:A new method based on elements and chemical bonds was developed for estimating the normal boiling point of organic compounds.On the basis of 4 060 kinds of credible experimental data,7 correlations were obtained by regression.The average relativeerror was 3.63%,less much than mostly used group-contribution methods for alkyne,chlorine derivative,iodine derivative,especially for alkane,bromine derivative,aromatic hydrocarbon,alicyclic hydrocarbon and sulfur-containing organic compounds.
Keywords:t:he normal boiling point  estimatione  lementsc  hemical bonds  group-contribution techniques
