Standard Test Method for Determination of Olefin Content of Gasolines by Supercritical-Fluid Chromatography
|Publication Date:||1 November 2005|
|ICS Code (Liquid and solid fuel burners):||27.060.10|
This test method covers the determination of the total amount of olefins in blended motor gasolines and gasoline blending stocks by supercritical-fluid chromatography (SFC). Results are expressed in terms of mass % olefins. The application range is from 1 to 25 mass % total olefins.
This test method can be used for analysis of commercial gasolines, including those containing varying levels of oxygenates, such as methyl tert/butyl ether (MTBE), diisopropyl ether (DIPE), methyl tert/amyl ether (TAME), and ethanol, without interference.
NOTE 1-This test method has not been designed for the determination of the total amounts of saturates, aromatics, and oxygenates.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
