Three-phase hydrogenation of nitrobenzene

A further interesting approach for the simultaneous in situ monitoring of the liquid phase and the soUd/Uquid catalyst interface during the three-phase hydrogenation of nitrobenzene (NB) over nanosized Au/Ti02 is reported by Richner et al. [15]. The setup that is described in detail later enables independent ATR-FTIR measurements of the liquid phase (detection of NB conversion and intermediates) using a probe and of the soUd/hquid interface by immobilizing the catalyst on a bottom-mounted ATR crystal.
