Historical Standard: ASTM D4424-90(2001)e1 Standard Test Method for Butylene Analysis by Gas Chromatography
SUPERSEDED (see Active link, below)
ASTM D4424
1. 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 X1 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 S1units 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 problems 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.
