Abstract: The present invention relates to a continuous process for the preparation of cinnamaldehyde or cinnamaldehyde derivatives by continuous reaction of benzaldehyde derivatives with alkanals in the presence of bases and optionally subsequent continuous hydrogenation in a circulation reactor in the presence of a suspension catalyst and hydrogen to give dihydrocinnamaldehyde derivatives.

Abstract: The invention relates to a continuous method for production of cinnamaldehyde or cinnamaldehyde derivatives comprising continuous reaction of benzaldehyde derivatives with alkanals in the presence of bases and, optionally, as the final step, continuous hydrogenation in a recirculating reactor in the presence of a suspended catalyst and hydrogen to give dihydrocinnamaldehyde derivatives.
