| 摘 要： | 测定T2-甲基戊烷、3-甲基戊烷和正乙烷在293．15－318．15K温度范围的热压力系数．一个根据对应状态原理建立的模型被用来描述链烷烃的内压，它们的模型参数能很好地用分子连通指数关联．用这种方法能预测各种链烷烃从三相点到临界点广阔温度范围的内压．

| Abstract: | The thermal pressure coefficients of 2-methylpentanwe,3-methylpentane and n-hexaneover the temperature range of 293.15~318.15K have been measured,A model based on corre-spending state principle is used to descrbe internal pressures of alkanes .The parameters of the model are well correlated with molecular connectivity indices,It is shown that this method can be used to predict internal pressures of various alkanes over wide temperature range from triple point to critical point. |
