摘　　要：为了获得煤液化油窄馏分准确的物性参数——蒸气压,比较分析了物质蒸气压的测量、关联及估算方法。详细分析了几种测定方法的理论依据、设备要求及使用范围。根据煤液化油窄馏分的组分特性,提出了适用于其馏分饱和蒸气压测量关联及估算的方法。研究发现:窄馏分蒸气压的测量宜选择拟静态法,也可以参照石油馏分蒸气压的测量选用雷德法和参比法。其蒸气压与温度的关联应使用三参数Antoine方程;修正的MB关联式和Riedel方程适用于煤液化油窄馏分蒸气压估算。To get accurate saturated vapor pressure of coal liquefied fractions, analyse its measure, correlation and estimate methods. The theoretical basis, facility requirement and application range of these methods are investigated in detail. Considering the characteristics narrow fraction in coal liquefied oil, provide the suitable saturated vapor pressure measure and correlation method. The results show that, the proper method is static one, Reid Vapor Pressure （RVP） method and reference method are also great ones if consulted the measure method for saturated vapor pressure of petroleum fraction. Three-parameter equation could interrelate the vapour pressure and temperature. Correctional MB correlation and Riedel equation are appropriate for saturated vapor pressure estimation of narrow fraction.
