Full Description

1.1This test method covers the gas chromatographic analysis of commercial butylenes, butylene concentrates, and butane-butylene mixtures.

1.2This 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.

1.3This 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.

1.4The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are for information only.

1.5This 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.
