The authors apply Raman spectroscopy in a study of the hydrogenation of acetophenone (ACP) on fused iron catalysts. This reaction was selected because the catalyst has advantages in the production of alcohols by selective hydrogenation of aldehydes and ketones. Also, the ACP has a sufficiently intense Raman spectrum. The studies were performed in a specially designed high-pressure heated cell made of stainless steel with windows of fused optical quartz for introduction of the exciting laser beam and collection of the scattered radiation. The results obtained demonstrate that it is possible in principle to apply Raman spectroscopy in investigating the structure of intermediates on a catalyst surface in situ. Broad prospects exist for the application of Raman spectroscopy, first of all in the investigation of mechanisms of heterogeneous catalytic reactions under conditions of practical catalysis (high temperatures and pressures).
