Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the National Standardization Technical Committee for Petroleum Products and Lubricants (SAC/TC280). This standard by the National Petroleum Products and Lubricants Standardization Technical Committee of Petroleum Fuels and Lubricants Subcommittee (SAC/TC 280/SC1). This standard is drafted by China Petroleum & Chemical Corporation Petrochemical Research Institute, China Petroleum & Chemical Corporation Yanshan Branch, China Petroleum & Chemical Corporation Qilu Branch Research Institute, University of Petroleum (Beijing) and China Petroleum & Chemical Co., Ltd. Company Beijing Chemical Industry Research Institute to participate in the drafting. The main drafters of this standard. Liu Ze Long, Yang Tingting. Isolation and Determination of Aromatic Components in Middle Distillates Solid phase extraction - gas chromatography WARNING - This standard does not advise on all safety concerns involved. Users of this standard should establish appropriate safety before use Full protective measures and to determine the applicability of the relevant regulatory limits.

1 Scope

This standard specifies the use of solid phase extraction - gas chromatography separation and determination of middle distillates, including fatty acid methyl ester in the aromatic hydrocarbon group Fraction, a non-aromatic component and a fatty acid methyl ester component. This standard applies to middle distillates in the range of 170 ° C to 400 ° C, including diesel oils containing less than 10% by volume of fatty acid methyl esters. This standard is divided into method one and method two. Method 1 is suitable for the middle distillate containing no fatty acid methyl ester. Method 2 is suitable for containing fatty acids Methylation volume of less than 10% diesel. This standard applies to the determination of aromatic components containing aromatic components of 4% to 50% of the middle distillate samples, containing fatty acid methyl ester component fraction For 2% to 10% diesel samples. Samples beyond this range of content This standard can also be measured, but no precision data is given. In the analysis of this standard method, aromatic hydrocarbons include thiophene sulfur compounds, nitrogen compounds and oxygen compounds; according to the standard method In the case of the two analyzes, the nitrogen-containing compounds and the oxygen-containing compounds included in the fatty acid methyl ester component may have an effect on the results.
