| 摘要 |
The invention relates to a process for synthesizing a nitrile-fatty acid (heminitrile) from unsaturated fatty acids, in the form of an acid or a simple ester or a "complex" ester of triglyceride type, which is first of all converted into an unsaturated fatty nitrile which is subjected to oxidative cleavage using H2O2 as oxidizing agent. This process can be used for preparing polyamide monomers, such as omega-amino acids or diamines or diacids equivalent to said heminitrile and for obtaining polyamides from raw materials which are of natural origin and from a renewable source. |
