Patent
CA 2303776
The invention relates to a catalyst, comprising at least one nickel (O) complex containing at least one monodentate, bidentate or multidentate phosphonite ligand of general formula (I) or the salts or mixtures thereof. The invention also relates to a method for producing said catalysts and to a method for producing monoolefinic C5-mononitriles with a non conjugated C=C and CN -bond by catalytic hydrocyanation of butadiene or a hydrocarbon mixture containing 1.3 butadiene, characterised in that hydrocyanation occurs in the presence of one such catalyst.
L'invention concerne un catalyseur comprenant au moins un complexe nickel(O) contenant au moins un ligand de phosphonite bi- ou polydenté de la formule générale (I), ou ses sels ou ses mélanges. L'invention concerne également un procédé permettant de préparer lesdits catalyseurs. L'invention concerne en outre un procédé de préparation de mélanges de mononitriles C¿5? mono-oléfiniques avec une liaison C=C et C?N non conjuguée, par hydrocyanation catalytique de butadiène ou d'un mélange hydrocarbure contenant du 1,3-butadiène. Ce procédé se caractérise en ce que l'hydrocyanation s'effectue en présence d'un catalyseur de ce type.
