Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Petroleum Products and Lubricants Standardization Technical Committee (SAC/TC280). This standard was drafted. Petrochemical Research Institute of China Petroleum and Chemical Corporation, China Petroleum and Chemical Corporation Sea Petrochemical Research Institute, PetroChina Research Institute of China National Petroleum Corporation. The main drafters of this standard. Wang Wei, Li Chengzhen, Shi Dejun. Determination of fatty acid methyl ester content in aviation turbine fuel Gas chromatography-mass spectrometry Caution - Personnel using this standard should have practical experience in formal laboratory work. The use of this standard may involve certain dangers Materials, equipment and operations, this standard does not identify all possible safety issues. Users are responsible for taking appropriate safety and health measures And ensure that it meets the conditions stipulated by relevant national laws and regulations.

1 Scope

This standard specifies the test method for the determination of fatty acid methyl esters in aviation turbine fuels by gas chromatography-mass spectrometry. This standard applies to the determination of various fatty acid methyl esters derived from biodiesel in aviation turbine fuels (see Table 1), total fatty acid methyl esters. The content range is from 4.5 mg/kg to 140 mg/kg. Note 1. Aviation turbine fuel (and aviation turbine fuel contaminated by diesel or biodiesel) may contain some hydrocarbon components with higher molecular weight. These components mask the peaks of trace fatty acid methyl esters. Low-carbon fatty acid methyl esters, such as fatty acid methyl esters obtained from coconut oil, are subject to aviation The interference of some heavy components in the empty turbine fuel cannot be quantitatively determined at low levels. Note 2. This standard mainly examines several fatty acid methyl esters listed in Table 1. The mass fraction of these fatty acid methyl esters in common biodiesel is generally 95%. the above. In addition, methyl heptadecanoate may be present in animal fats such as dairy products and egg yolk lecithin, and is therefore also included. Table 1 fatty acid methyl esters examined in this standard Fatty acid methyl ester CAS number formula representative symbol Methyl palmitate (methyl palmitate) 112-39-0 C17H34O2 C16.0 Methyl heptadecanoate (methyl methacrylate) 1731-92-6 C18H36O2 C17.0 Methyl octadecanoate (methyl stearate) 112-61-8 C19H38O2 C18.0 Methyl octadecenoate (methyl oleate) 112-62-9 C19H36O2 C18.1 Methyl octadecadienoate (methyl linoleate) 112-63-0 C19H34O2 C18.2 Methyl octadecatrienoate (methyl linolenate) 301-00-8 C19H32O2 C18.3

3 Method summary

After mixing the aviation turbine fuel sample with the internal standard, it is introduced into a gas chromatography-mass spectrometer (GC-MS) and then passed through a polar capillary. The column is separated to separate a small amount of the fatty acid methyl ester polar compound from the non-polar hydrocarbon compound which is the main component of the aviation turbine fuel. ......
