Analysis of Trace Hydrocarbon Impurities in 1,3-Butadiene

In this study trace impurities of 1,3-Butadiene are separated into both common light polar contaminants, including methyl acetylene and propadiene, as well as 4-vinylcy¬clohexene, which is a high molecular weight impurity. By using an extended temperature program 4-vinylcyclohexene, as well as all of the typical low molecular weight impurities, can be analyzed in a single test.
