摘要
根据分子结构的特点 ,通过区分烯烃与烷烃分子中基团的差别 ,借助于拓扑方法探讨了烯烃的沸点与分子结构之间的关系 ,将烷烃沸点计算公式推广用于烯烃沸点的计算 ,提出了一种计算烯烃沸点的新方法。对 2 0 1种烯烃的计算结果表明 ,沸点计算值与实验值的一致性令人满意 ,平均误差 0 .90 %。
Based on the characteristics of molecular structure,the relationship between the boiling point and molecular structure of alkene is studied by means of topology.In view of the differences in radical between alkane molecule and alkene molecule,a new method is put forth for calculatingthe boiling point of alkene——borrowing the formula for the calculation of thatof alkane.And the calculated boiling points of 201 kinds of alkene are almost the same as the experiment results,with a mean deviation of 0.90%
