In-Situ Laser Raman Spectroscopy Adapted to Process Conditions for Studying Cyclohexane Oxidation

Cyclohexane oxidation is an economically important process. To maintain high selectivities of 70 to 90%, the reaction is performed at low conversion up to 6%. To improve this process, investigations on the reaction mechanism are of high interest, which requires measurement techniques able to detect chemical species precisely even at very low concentrations. For this purpose, an in-situ measurement technique based on laser Raman spectroscopy with superior detection sensitivity and an optically transparent microchannel to monitor the process of cyclohexane oxidation has been developed.
