Process for the production of unsaturated villagers by aldolic condensation

摘要

B PROCESS FOR THE PRODUCTION OF ALDE D AID D Production of aldids unsaturated by the aldylic condensation of linear-chain villagers, e.g. butyrldehyde, contact of the aldehyde in the steam phase with a particle catalyst comprising at least one basic alkaline metal compound supported on an inert substrate at a temperature above 175.C.
