Acta Petrol Sinica, 2014.04. | Determination of methylal, dimethyl carbonate, secbutyl acetate, isobutyl acetate and n-methyl aniline in gasoline by two-dimensional gas chromatography method.[Reference: WebLink] | METHODS AND RESULTS: The separation of the five unconventional components,methylal,dimethyl carbonate,sec-butyl acetate,Isobutyl acetate and N-methyl aniline in motor gasoline,which were hard to be separated from gasoline components only by non-polar capillary column,was carried out by twodimensional gas chromatography.In the two-dimensional gas chromatography the five compounds were cut to the second capillary column to be separated and determined by FID detector and internal standard method.
CONCLUSIONS:
The results showed that the five compounds were well separated from gasoline components with the recovery rate range of 97.9%-102.2%,the relative standard deviation of less than 2.0%and the detection limit of 0.01%(mass fraction),meaning that the quantitative data were accurate and reliable.The repeatability and reproducibility of the method can meet the requirements for routine analysis. |
