Reaktionsschritte

The ethenolysis of the nitrile of oleic acid is carried out at 60° C. under atmospheric pressure in the presence of a ruthenium-based catalyst, [RuCl2(═CHPh)(IMesH2)(PCy3)], using an excess of ethylene, to give 9-decenoic acid, CH2═CH—(CH2)7—COOH. The yields are determined by chromatographic analysis. At the end of the reaction, 6 hours, the C10 α-olefin is separated by vacuum distillation, to give the 9-decenoic nitrile CH2═CH—(CH2)7—CN. The yields are determined by chromatographic analysis. It is possible to measure a yield of 55%.
