| Abstract: | The method to determine dimethyl ether,methanol and dimethoxymethane content in the liquefied petroleum gas is developed by using capillary gas chromatography and constant temperature water bath to gasify samples.Using PLOT/Q（30 mm×0.53 mm×40 μm）capillary column and TCD detector,the impurity content is calculated by area calibration normalization method.The results show that the method has advantages of simple operation,practicability,good repeatability,and can be used to analyze the impurity content in liquefied petroleum gas. |
