On-line mid-IR spectroscopy as a real-time approach in monitoring hydrogenation reactions

The use of mid-IR. spectroscopy as a real-time monitoring tool for hydrogenation reactions is illustrated. This technique was used for both qualitative and quantitative purposes to monitor the hydrogenation of three different functional groups. The results show that this technique can be successfully used as an alternative to traditional off-line methods to monitor the reaction endpoint and the formation of impurities.
