摘要
介绍了各种对物质饱和蒸气压测定的方法,给出了各种方法的适用范围及其优缺点。特别分析了蒸气压的现代测量方法(色谱法、热重法和差示扫描量热法)和工厂常用的雷德法的特点,得出性质较为复杂的煤液化油馏分饱和蒸气压的测定宜采用拟静态法。
advantages and methods （gas c Measurement methods of saturated vapor pressure for liquid samples were reviewed, their adaptive ranges, disadvantages and the key factors of experimental operations were also pointed out. Modern measuring hromatography, thermogravimetry, differential scanning calorimeters） and Reid methods were analyzed in particular. The method of measuring vapor pressure of fraction from coal liquefaction oil was also discussed.
