摘要：The thermal pressure coefficients of 2-methylpentane, 5-methylpentane and n-hexane over the temperature range of 293.15 similar to 318.15K have been measured. A model based on corresponding state principle is used to describe 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.
