Industrial Propylene. Determination of Hydrocarbon Impurities. Gas Chromatography (1)

1 Scope

1.

Since this standard cannot determine all possible impurities, such as hydrogen, oxygen, carbon monoxide , carbon monoxide , water, oligomers, and alcohol compounds, other test methods are required to fully characterize propylene samples
