1. 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, 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.
