METHOD FOR PREPARING LONG-CHAIN HYDROXYACIDS, DIACIDS AND OLIGOMERS AND POLYMERS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing ricinoleic acid analogs and oligomers and polymers containing such ricinoleic acid analogs.SOLUTION: The present invention relates to the preparation method, wherein a substance is selected from a group consisting ofω-hydroxy fatty acids andα,ω-dicarboxylic acids with carbon chain lengths from C14 to C22, and the substance is transformed toω-hydroxy orω-carboxy ricinoleic analog or to a mixture ofω-hydroxy andω-carboxy ricinoleic analogs by a biocatalytic step. The present invention relates to the method, wherein biocatalysts, which are capable of producing P450 mono-oxygenase, are microorganisms, such as Candida tropicalis, Candida cloacae, Cryptococcus neoformans, and Corynebacterium sp. The present invention relates to the method further comprising a step of using the ricinoleic acid analogs as monomers for oligomer and polymer synthesis.
