The subject matter of the invention is a process for synthesizing a saturated long-chain &#x3b1;,&#x3c9;-amino ester (acid) obtained in a first step by cross-metathesis between an acrylic first compound and a monounsaturated second compound comprising at least one nitrile, acid or ester trivalent function, one of these compounds comprising a nitrile function and the other an acid or ester function, in the presence of a ruthenium carbene metathesis catalyst, and in a second step by hydrogenation of the monounsaturated nitrile ester (acid) obtained in the presence of the metathesis catalyst of the preceding stop, acting as a hydrogenation catalyst.

Process for preparing saturated amino acids or saturated amino esters comprising a metathesis step

A process is described in which an unsaturated fat is reacted with ethylene in a metathesis reaction in the presence of at least one non-aqueous ionic liquid to produce both an olefinic fraction and a composition of monoalcohol or polyol esters. Particular application to an oleic sunflower seed oil, an oleic rapeseed oil or to a mixture of monoalcohol esters of said oils, the process producing both an olefinic fraction and a monoalcohol or glycerol esters composition generally having more than half of its chains constituted by unsaturated Cchains.

Process for co-producing olefins and esters by ethenolysis of unsaturated fats in non-aqueous ionic liquids
