摘要
在以前工作的基础上，建立了直链烷烃热压力系数与链长的关系式，得到了直链烷烃的恒温压缩系数、恒压与恒容比热容之差和内压力，并对这些性质与温度和链长的关系进行了讨论。
Based on our previous work,a relation between the thermal pressure coefficient and the chain length for normal alkanes is established,which is applicable to a wide temperature range,i.e.,from the triple points to the critical points.Furthermore,the isothermic coefficients of compressibility β,differences in heat capacities C P-C V and internal pressures P i at three temperatures are calculated respectively for various normal alkanes,and their variations with chain length and temperature are discussed.
