ABSTRACT:
The use of a fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of azelaic acid or for the production of diperazelaic acid from the azelaic acid thus produced, with elimination of enrichment steps with respect to the oleic acid content, by fat splitting, distillation, oxidative ozonolysis of the fatty acid mixture obtained, and in the case of production of diperazelaic acid by reaction of the azelaic acid thus obtained with hydrogen peroxide to form diperazelaic acid. The resulting diperazelaic acid has improved stability in storage and is obtained in high yields and in highly pure form.
