摘要:
The invention relates to a process for preparing sorbic acid by thermal cleavage in a solvent of the polyester prepared from crotonaldehyde and ketene, the cleavage of the polyester being carried out in the presence of 20 to 100% by weight of a secondary or tertiary aliphatic, alicyclic nitrogen- and/or oxygen-containing amine, or aliphatic-aromatic substituted amine, as catalyst.
