1.1 This test method covers the determination of butadiene-1,3 purity and impurities such as propane, propylene, isobutane, n<\/span> -butane, butene-1, isobutylene, propadiene, trans<\/span> -butene-2, cis<\/span> -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.<\/p>\n

Note<\/span> 1Other impurities present in commercial butadiene must be calibrated and analyzed. Other impurities were not tested in the cooperative work on this test method.<\/p>\n

Note<\/span> 2This test method can be used to check for pentadiene-1,4 and other C 5<\/sub> s instead of Test Method .<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

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 and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.1 and 9.3.<\/span><\/span><\/p>\n
