Title (EN) METHOD FOR PRODUCING NITRILE COMPOUNDS FROM ETHYLENICALLY UNSATURATED COMPOUNDS
(FR) PROCEDE DE FABRICATION DE COMPOSES NITRILES A PARTIR DE COMPOSES A INSATURATION ETHYLENIQUE
Abstract: front page image
(EN)The present invention relates to a method for the hydrocyanation of organic ethylenically unsaturated compounds including at least one nitrile function. The invention specifically relates to a method for the hydrocyanation of a hydrocarbon compound including at least one ethylenic unsaturation by a reaction with hydrogen cyanide in a liquid medium and in the presence of a catalyst including a metal element selected from the transition metals and an organophosphorous ligand, the organophosphorous ligand including a compound of general formula (I), where R1 and R2, which are identical or different, are a linear or branched alkyl radical having 1-12 carbon atoms, which can include heteroatoms, or an optionally substituted aromatic or cycloaliphatic radical that can include heteroatoms, wherein the covalent bond between P and R1, and that between P and R2, are P-C bonds.
(FR)La présente invention concerne un procédé d'hydrocyanation de composés organiques à insaturation éthylénique en composés comprenant au moins une fonction nitrile. Elle concerne plus particulièrement un procédé d'hydrocyanation d'un composé hydrocarboné comprenant au moins une insaturation éthylénique par réaction en milieu liquide avec le cyanure d'hydrogène en présence d'un catalyseur comprenant un élément métallique choisi parmi les métaux de transition et un ligand organophosphoré, le ligand organophosphoré comprenant un composé répondant à la formule générale (I): dans laquelle R1 et R2, identiques ou différents, représentent un radical alkyl linéaire ou ramifié ayant de 1 à 12 atomes de carbone pouvant contenir des hétéroatomes, ou un radical comprenant un radical aromatique ou cycloaliphatique substitué ou non pouvant comprendre des hétéroatomes la liaison covalente entre P et R1 d'une part, et celle entre P et R2 d'autre part, sont des liaisons P-C
