Catalytic distillation experiments were designed and carried out in a pilot-scale column to prove the technical feasibility of the heterogeneously catalyzed n-propyl propionate synthesis by esterification of propionic acid with 1-propanol using the surface-sulfonated ion-exchange resin Amberlyst 46. The experiments cover a broad range of decisive operational parameters, for example, reflux ratio, column load, distillate-to-feed ratio, and molar feed ratio of the reactants. The reconciled results comprise a complete set of concentration and temperature profiles along the column height and, hence, exhibit detailed and reliable data for model validation purposes.

A set of experimental data for heterogeneously catalysed esterification of propan-1-ol and propionic acid to propyl propionate in a pilot scale reactive distillation column is presented. The catalytic section of the column was equipped with the structured packing Katapak SP-11. Both, rectifying and stripping, sections consisted of the non-reactive structured Sulzer BX packing. As catalyst, the strongly acidic ion-exchange resin Amberlyst 46 was used. The experimental results show concentration as well as temperature profiles along the column height and therefore exhibit reliable data for model validation purposes.
