Standard Test Method for Butadiene Purity and Hydrocarbon Impurities by Gas Chromatography
Standard Test Method for Butadiene Purity and Hydrocarbon Impurities by Gas Chromatography
SIGNIFICANCE AND USE 4.1 The trace hydrocarbon compounds listed can have an effect in the commercial use of butadiene. This test method is suitable for use in process quality control and in setting specifications. SCOPE 1.1 This test method covers the determination of butadiene-1,3 purity and impurities such as propane, propylene, isobutane, n-butane, butene-1, isobutylene, propadiene, trans-butene-2, cis-butene-2, butadiene-1,2, pentadiene-1,4, and, methyl, dimethyl, ethyl, and vinyl acetylene in polymerization grade butadiene by gas chromatography. Impurities including butadiene dimer, carbonyls, inhibitor, and residue are measured by appropriate ASTM procedures and the results used to normalize the component distribution obtained by chromatography. Note 1: Other impurities present in commercial butadiene must be calibrated and analyzed. Other impurities were not tested in the cooperative work on this test method. Note 2: This test method can be used to check for pentadiene-1,4 and other C5s instead of Test Method D1088. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. For specific warning statements, see 6.1 and 9.3. 1.3.1 The user is advised to obtain LPG safety training for the safe operation of this test method procedure and related activities. 1.4 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.
ASTM D2593-23: Standard Test Method for Butadiene Purity and Hydrocarbon Impurities by Gas Chromatography establishes procedures for determining the purity of butadiene-1,3 and quantifying trace hydrocarbon impurities in polymerization-grade butadiene using gas chromatography. This internationally recognized standard, published by ASTM International, is essential for process quality control and setting product specifications within the chemical and petrochemical industries. The method is designed to identify and measure various hydrocarbon constituents and impurities that can significantly impact the commercial use and polymerization performance of butadiene.
