Abstract

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.
