Abstract
A process for preparing sebacic acid by reacting in a first step (i) linoleic acid with water catalyzed by an oleate hydratase to form 10-hydroxy-12-octadecenoic acid, in a second step (ii) pyrolysing the 10-hydroxy-12-octadecenoic acid to 1-octene and 10-oxo-decanoic acid and in a third step (iii) oxidizing the 10-oxo-decanoic acid to sebacic acid.
Claims12
A process for preparing sebacic acid comprising
- in a first step reacting (i) linoleic acid with water catalyzed by an oleate hydratase to form 10-hydroxy-12-octadecenoic acid,
- in a second step (ii) pyrolysing the 10-hydroxy-12-octadecenoic acid to 1-octene and 10-oxo-decanoic acid, and
- in a third step(iii) oxidizing the 10-oxo-decanoic acid to sebacic acid, wherein the oleate hydratase is a polypeptide having the amino acid sequence depicted in SEQ ID NO:2 or an amino acid sequence which is at least 95% identical to the amino acid sequence depicted in SEQ ID NO:2.
