    摘要: In the hydrocyanation reaction of butadiene proceeding through pentenenitriles to adiponitrile, catalysis by complexes of zerovalent nickel with bidentate phosphorus-based ligands of the NiL 2 A type wherein L 2 is a bidentate ligand and A is an unsaturated compound, can be rate-limited by the solubility of the catalytic complex. The present invention concerns solvent compositions for the nickel-ligand complex comprising mixtures of unsaturated nitriles that provide for increased metal solubility, particularly in the absence of a Lewis acid promoter, resulting in higher hydrocyanation reaction rates in an industrial-scale process for production of important nylon manufacturing intermediates. The mixed nitrile solvent compositions can include mixtures of pentenenitriles and/or methylbutenenitriles. The mixtures of mixed unsaturated nitriles can be, at least in part, from recycle streams from the hydrocyanation reaction for which the nickel-bidentate ligand complexes are used as catalysts.

    摘要: The invention provides a method of forming a phosphonate diester compound from a ligand hydrolysis product (LHP) of a phosphite ligand used in a nickel-phosphite hydrocyanation catalyst, such as for conversion of 3-pentenenitrile to adiponitrile, which serves to eliminate acidic LHP compound for a hydrocyanation reaction milieu where the acidic LHP can catalyze further catalyst ligand destruction. The invention further provides phosphonate disester compounds prepared by alkylation of diarylphosphite LHP in the presence of a nickel-phosphite catalyst comprising a bidentate ligand, and a continuous hydrocyanation process for production of adiponitrile wherein catalyst ligand breakdown is inhibited through inactivation of ligand hydrolysis products towards further breakdown. A method of stabilizing a hydrocyanation catalyst is provided.
