Optimization of reaction conditions and effect of catalyst type on product distribution in Cyclooctene oxidation

Abstract

<span style="font-size: 12.16px; line-height: 1.3em;">Oxidation of cyclooctene was studied in presence aqueous hydrogen peroxide (30%, v/v) over nano iron oxide. The catalyst prepared by microemulsion method and characterized using various techniques including XRD, TEM and BET techniques for evaluating phase, structure and morphology and surface area. In this study, we investigated the effects of varying the catalyst content, reaction temperature, H</span><sub style="line-height: 1.3em;">2</sub><span style="font-size: 12.16px; line-height: 1.3em;">O</span><sub style="line-height: 1.3em;">2</sub><span style="font-size: 12.16px; line-height: 1.3em;"> to cyclooctene molar ratio, reaction temperature and solvent. Epoxycyclooctane was found to be the main reaction product, along with amounts of other products. The best result for epoxycyclooctane production is obtained using acetonitril as solvent at 78 </span><sup style="line-height: 1.3em;">o</sup><span style="font-size: 12.16px; line-height: 1.3em;">C for a 16 h reaction period with 0.32 g nano-sized iron particle catalyst.
