Application of In Situ Raman Spectroscopy To Facilitate Use of Hydrogen Peroxide on Kilogram Scale

The safe implementation of a hydrogen-peroxide-mediated oxidation of a poorly reactive sulfide to the corresponding sulfone is described. A three-tiered approach incorporating process understanding, safety studies, and real time PAT (in situ Raman spectroscopy) was leveraged to ensure safe operation. Further investigation of an in situ Raman spectroscopy model for the reaction and its use for in-process control and end-point determination is discussed.
