[Gas chromatography-infrared spectroscopy(GC-IR) analysis of the oxidation products of cyclohexene].
Gas chromatography-infrared spectroscopy technique integrates the excellent resolution ability of GC with the structural information of IR. Based on the GC and IR spectra, the complicated products of a reaction can be analyzed quantitatively and qualitatively. From the analysis of the products, the reaction process and its mechanism can be elucidated. In this work, analysis by GC-IR of the oxidation products of cyclohexene catalyzed by zeolite TS-1 in H2O2 was performed. The products are 2-cyclohexenone, 2-cyclohexen-1-ol and 2,3-epoxy-1-cyclohexanone. 2,3-Epoxy-1-cyclohexanone is an unexpected product. It must be a further oxidation product of 2-cyclohexenone. From the analysis, the reaction mechanisms were presumed.
