METHOD FOR THE COPRODUCTION OF METHYL 7-OXOHEPTANOATE AND UNDECYLENIC ACID FROM RICINOLEIC ACID |
摘要 |
The invention relates to a method for converting ricinoleic acid, that comprises the following successive steps: a) fermentation of the ricinoleic acid with a bacterium, a yeast or a fungus in order to obtain 7-hydroxy-9-octadecenedioic-diacid; b) esterification of the 7-hydroxy-9-octadecenedioic-diacid obtained during step a) in order to form the corresponding methylic diester; high temperature cracking of the product obtained during step b) in order to form a mixture of methyl undecylenate and methyl 7-oxoheptanoate; d) separating the methyl undecylenate from the methyl 7-oxoheptanoate obtained during step c); e) hydrolysing the methyl undecylenate obtained during step d) for forming the undecylenic acid. |
