<p>A process for the synthesis of an unsaturated product by cross metathesis between a first unsaturated compound having at least 8 carbon atoms and a second unsaturated compound having less than 8 carbon atoms, including: feeding a reactor with the first unsaturated compound, the second unsaturated compound and a metathesis catalyst; withdrawing an output stream, at the output of the reactor; separating the output stream, making it possible to recover at least: on the one hand, the unsaturated product and, on the other hand, the first unsaturated compound and the second unsaturated compound; recycling the first unsaturated compound and the second unsaturated compound to the reactor; in which the first unsaturated compound is capable of producing an unsaturated coproduct, including at least 14 carbon atoms, by homometathesis; and in which the flow rates for feeding the reactor with first unsaturated compound and with second unsaturated compound are adjusted.</p> |
