摘要
以烷烃同系列碳原子数值连续变化为模型 ,提出了一个新的预测烷烃同系物正常沸点的经验公式 :Tb =aln(N +b) +ca、b、c均为常数 ,N为烷烃碳原子数。用上式计算了 5个系列 91个烷烃的沸点 ,平均绝对误差为 0 .79K ,平均相对误差 0 .1 5% ,标准方差为 0 .91
Based on the model of the continuous change of the numerical value of carbon atoms in the series of paraffin,a new empirical equation is derived as follows,which can be used to predict the normal boiling point of paraffin homologen. T b=aln(N+b)+c a,b and c stand for constans,N stands for paraffin carbon atom number.By the equation,91 paraffin boiling points in 5 series have been calculated,the average absolute error is 0.79K,the average relative error is 0.15 percent the standard variance is 0.9180K.
