Aldol condensation of benzaldehyde and heptanal: a comparative study of laboratory and industrially prepared Mg-Al mixed oxides
Original language description
Several layered double hydroxides (with Mg:Al ratio varying from 2:1 to 4:1) were prepd. by a co-pptn. method at const. pH value. The activity of lab. prepd. samples was compared with that of industrially prepd. layered double hydroxides with the same Mg/Al ratio in aldol condensation of benzaldehyde with heptanal. Characterization of all solid catalysts was performed using different techniques (ICP-MS, thermogravimetry, X-ray diffraction, DRIFT spectroscopy, nitrogen physisorption method, SEM). Acid-base properties of prepd. materials were investigated using ammonia (carbon dioxide, resp.) temp. programmed desorption. Heptanal conversion and selectivity to two main products, i.e., 2-pentylcinnamylaldehyde (jasmine aldehyde) and 2-pentylnon-2-enal, were monitored. All catalysts resulted in heptanal conversions higher than 95%. The highest selectivity to jasmine aldehyde (66% at 70% heptanal conversion, 46% theor. yield) was obtained using ESM 3:1 catalyst (100°, heptanal:benzaldehyde = 1:2 M, solvent-free synthesis).
