Standard Test Method for Butadiene Purity and Hydrocarbon Impurities by Gas Chromatography

Scope

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.
