Abstract
Aldol condensation of butyraldehyde catalysed by aluminium, iron and chromium sesquioxides has been studied in the liquid phase at temperatures from 160 °C to 210 °C, using a plug-flow stainless steel reactor. Relationships between the activity of the catalysts, surface concentrations of basic sites and the butyric acid concentration in butyraldehyde were determined. The catalytic activity depended both on the surface concentration of basic sites and on their basicity; the latter increased in the sequence Fe2O3 ##i Cr2O3 < Al2O3.
