(Test Method)Standard Test Method for Determination of Butanol and Acetone Content of Butanol for Blending with Gasoline by Gas Chromatography
Standard Test Method for Determination of Butanol and Acetone Content of Butanol for Blending with Gasoline by Gas Chromatography
SIGNIFICANCE AND USE
5.1 Butanol is being approved for blending with gasoline in accordance with Specification D7862. This test method provides a method of determining the percentage of butanol (purity) of the butanol for blending with gasoline.
SCOPE
1.1 This test method covers the determination of the butanol content of butanol for blending with gasoline by gas chromatography.
1.2 Butanol is determined from 95 % to 99.9 % by mass, acetone is determined from 0.02 % to 1.5 % by mass, ethanol is determined from 0.02 % to 1.5 % by mass, and methanol is determined from 0.02 % to 1.5 % by mass. Equations used to convert these individual components from mass percent to volume percent are provided. This test method has not been evaluated for use with the butanol isomer 2-methyl-2-propanol.
1.3 This test method identifies and quantifies acetone, ethanol, and methanol, but does not purport to identify all individual components that may be present in butanol for gasoline blending.
1.4 Water cannot be determined by this test method and shall be measured by a procedure such as Test Method D1364 and the result used to correct the chromatographic values.
1.5 This test method is inappropriate for impurities that boil at temperatures higher than 225 °C or for impurities that cause poor or no response in a flame ionization detector, such as water.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
