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。 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.
