摘要

The present invention relates to a process for the catalytic aldol condensation of aldehydes, in particular for preparing α,β-unsaturated aldehydes, in a multiphase reactor.

主权项

1. A process for the catalytic aldol condensation of at least one aldehyde in a two-phase liquid reaction mixture in a reactor which has a reaction zone and a disengagement zone located directly above the reaction zone, wherein an aldehyde-comprising phase dispersed in a continuous aqueous catalyst-comprising phase is produced and a stream of the two-phase reaction mixture is allowed to rise from the reaction zone into the disengagement zone and coalesce, with a continuous organic phase being formed in the upper region of the disengagement zone.
