A method for the combined synthesis of a mono-unsaturated nitrile-ester(acid) and of a bi-functional carbonyl compound, wherein it includes a step including the cross metathesis mc1 of an unsaturated fatty acid/ester compound with an unsaturated nitrile compound, in which mc1 is performed with partial conversion such as to obtain and recover, separately, at least the following products: a mono-unsaturated nitrile-ester/acid and a symmetrical compound, diester or diacid respectively including a double bond located in the middle of the molecular chain of compound, and subsequently a step including the oxidation cleavage cp2 of the double bond of compound, such as to form a single type of carbonyl compound having formula R2-(CH2)n-COR′, in which R′ is H or OH, depending on the operating conditions selected for the oxidation cleavage cp2. Also, the production of monomers for the polymer industry.
一种用于合成单不饱和腈酯(酸)和双官能羰基化合物的联合合成方法,其中包括一步骤,包括将不饱和脂肪酸/酯化合物与不饱和腈化合物进行交叉重排mc1的步骤,其中mc1是以部分转化进行的,以便分别获得和回收至少以下产品:单不饱和腈酯/酸和对称化合物,二酯或二酸,分别包括分子链中间位置的双键,并随后包括氧化裂解化合物的双键的步骤cp2,以形成具有化学式R2-(CH2)n-COR′的一种类型的羰基化合物,其中R′为H或OH,取决于选择用于氧化裂解cp2的操作条件。此外,用于聚合工业的单体的生产。
