饱和烷烃的内压与临界参数

Internal Pressures and Critical Parameters for Paraffins

根据对应状态原理,建立了一个能由临界参数和偏心因子预测饱和烷烃在各种温度下热压力系数及内压的方法,对34种正构和异构饱和烷烃预测的结果表明,内压的计算值与实验值的平均相对误差约为±1.8%。

According to corresponding-state principle, a method which can be used to predict the thermal pressure coefficients and internal pressures of paraffins at various temperatures from critical parameters and acentric factors is established. The predicted results of internal pressure show that the average relative deviation from experimental values is about±1.8% for thirty-four normal and isomeric paraffins.
