  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 H 2 O 2 as oxidizing agent. This process can be used for preparing polyamide monomers, such as ω-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.

  该发明涉及一种从不饱和脂肪酸合成一种腈基脂肪酸（半腈）的方法，该脂肪酸以酸或简单酯或三酸甘油酯型“复合”酯的形式存在，首先转化为不饱和脂肪腈，然后使用H2O2作为氧化剂进行氧化裂解。该方法可用于制备聚酰胺单体，如ω-氨基酸或二胺或与所述半腈等效的二酸，并从天然来源和可再生来源的原材料获得聚酰胺。
