摘　　要：采用气相色谱、气相色谱质谱联用技术对M15甲醇汽油在不同温度点的挥发组分的分子组成进行分析。结果 表明：随温度的升高M15甲醇汽油与原料汽油饱和蒸汽压差值迅速增大，在实验温度范围内，差值在1～60 kPa之间；挥发组分主要由甲醇等30余种主要组分组成，占总挥发组分的90%以上。Volatile components of M15 methanol gasoline at different temperatures were analyzed by using gas chromatography, gas chromatography mass spectrometry technology. The results show that , with rise of the temperature,saturation vapour pressure difference of M15 methanol gasoline and raw material gas increases rapidly, within the scope of the experimental temperature, difference is in the range of 1 to 60 kPa. Volatile components are mainly composed of methanol and other more than 30 kinds of main components, accounting for over 90%of the total volatile components.
