ASTM D4424-09(2014)

Standard Test Method for Butylene Analysis by Gas Chromatography (Withdrawn 2023)

SIGNIFICANCE AND USE
4.1 This test method could be used to determine butylene stream composition for custody transfer payments. It is also capable of providing data necessary to evaluate processing requirements in an operating plant.
SCOPE
1.1 This test method covers the gas chromatographic analysis of commercial butylenes, butylene concentrates, and butane-butylene mixtures.  
1.2 This test method does not cover high-purity butene-1 or high-purity isobutene streams, or both. However, it is possible that one or more columns listed in Appendix X3 may be capable of the separation necessary for high-purity analyses.  
1.3 This test method is designed to cover the components listed below at about 0.05 % or greater. It is not intended for trace hydrocarbon analysis. Components to be determined are: propane, propylene, isobutane,  n-butane, butene-1, isobutene,  trans-butene-2,  cis-butene-2, 1,3-butadiene, isopentane,  n-pentane.  
1.4 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are for information only.  
1.5 This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  For specific warning statements, see 5.3.1.
WITHDRAWN RATIONALE
This test method covered the gas chromatographic analysis of commercial butylenes, butylene concentrates, and butane-butylene mixtures.
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in January 2023 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
