    • The invention relates to a conjugated process for the production of nitriles and/or of fatty amines and of polyol carbonates from a natural oil, comprising the following zones: I) zone of methanolysis or hydrolysis of a natural oil containing a triglyceride of at least one saturated or unsaturated fatty acid, producing, on the one hand, the methanolate of the fatty acid or the fatty acid and, on the other hand, glycerol, II) zone of synthesis of a fatty amine comprising the following steps: a) optional conversion, first of all, of the fatty acid methanolate to a fatty acid by hydrolysis of the ester derived from step I), followed in b) by an ammoniation reaction, with ammonia, of the acid or of the fatty acid methanolate derived from zone I or of the acid derived from step a), so as to form a nitrile, and then in c) by reduction, with hydrogen, of the compound resulting from step b), optionally in the presence of ammonia, so as to obtain the corresponding amine, III) zone of synthesis of a polyol carbonate by reaction of urea, either directly with glycerol, or with a diol obtained by reduction of glycerol by hydrogenation, wherein the reaction of the polyol with urea produces ammonia, IV) zone of recovery of the ammonia derived from zone III, and also that derived from zone Nb where the reaction is carried out with an excess of ammonia, and optionally that derived from zone Nc, so as to act as feed for the ammoniation of step b) in zone II and, optionally, the hydrogenation of step c) in zone II.
    • 本发明涉及用于生产腈和/或脂肪胺和来自天然油的多元醇碳酸酯的共轭方法,其包括以下区域:I)含有至少一种甘油三酯的天然油的甲醇分解或水解区 饱和或不饱和脂肪酸,一方面产生脂肪酸或脂肪酸的甲醇酸,另一方面,制备甘油,II)脂肪胺合成区,包括以下步骤:a)任选的转化 首先,通过水解来自步骤I)的酯的脂肪酸将脂肪酸甲醇化成脂肪酸,然后在b)中通过与氨或氨的氨化反应,得到酸或衍生自区域I的脂肪酸甲醇化物 或来自步骤a)的酸,以便形成腈,然后在c)通过用氢还原由步骤b)得到的化合物,任选地在氨存在下,得到相应的 胺,III)合成区 通过尿素直接与甘油反应或与通过氢化还原甘油获得的二醇反应,其中多元醇与尿素的反应产生氨,IV)来自区域III的氨的回收区, 并且还衍生自其中用过量的氨进行反应的区域Nb,以及任选地衍生自区域Nc的区域Nb,以便作为区域II中步骤b)的氨化的进料和任选的氢化 步骤c)在区域II。
