Purity analysis of 1-hexene using in-column hydrogenation gas chromatography
Pt hydrogenation catalyst was prepared with atomic layer deposition(ALD)technology,and then Pt hydrogenation micro-packed column was prepared.Through a six-way switching valve and a non-polar chromatographic column,the analytical method for 1-hexene purity and hydrocarbon impurities was established.Analysis of 1-hexene samples before and after hydrogenation was achieved by switching valves on a chromatograph.So,the separation of 1-hexene and 2-methyl-1-pentene on a single chromatographic column was achieved,and the purity of 1-hexene can be obtained through calculation.This study provides a new method for the separation of isomers and structural identification of other complex olefins in the petrochemical field.
