A method for synthesizing ω-amino-alkanoic acids or the esters thereof from natural unsaturated fatty acids passing through an intermediate ω-unsaturated nitrile compound. The method is simple to implement and, relative to known methods, avoids the environmental constraints and economic disadvantages resulting from the reaction by-products. The method includes synthesizing an ω-amino acid (ester) of formula R3OOC—(CH2)
q
—CH2NH2, in which R3 is H or an n-butyl radical and q is an integral index of between 2 and 13, from a monounsaturated fatty acid (ester) of formula (R1-CH═CH—(CH2)p-COO) xR2, in which x represents 1, 2 or 3, R1 is H or a hydrocarbon radical comprising from 4 to 11 carbon atoms and, where appropriate, a hydroxyl function, R2 is H or an alkyl radical comprising from 2 to 4 carbon atoms, and may contain one or more heteroatoms, and p is an integral index of between 2 and 11, including a reaction step of ammoniation.
一种从天然不饱和脂肪酸通过中间体ω-不饱和腈化合物合成ω-氨基-烷酸或其酯的方法。该方法实施简单,与已知方法相比,避免了由反应副产物导致的环境限制和经济劣势。该方法包括从公式为(R1-CH═CH—(CH2)p-COO)xR2的单不饱和脂肪酸(酯)合成公式为R3OOC—(CH2)q—CH2NH2的ω-氨基酸(酯),其中R3是H或n-丁基基团,q是2到13之间的整数指数,x代表1、2或3,R1是H或含4到11个碳原子的烃基团,适当情况下还含有羟基,R2是H或含2到4个碳原子的烷基基团,可包含一个或多个杂原子,p是2到11之间的整数指数,包括氨化反应步骤。
