    Abstract: Phosphorus-containing ligands are recovered from mixtures comprising 3-pentenenitrile (3PN) and adiponitrile (ADN), using liquid-liquid extraction. ADN is produced by hydrocyanation of 3PN. The ADN is hydrogenated to produce a hexamethyiene diamine (HMD) and at Ieast one byproduct including bis-hexamethylene triamine (BHMT) or 1,2-diaminocyclohexane. At Ieast a portion of the HMD product or byproduct is used to enhance the liquid-liquid extraction to recover phosphorus-containing ligand.

    Abstract: 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.

    Abstract: Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide. The 3- pentenenitrile is made by reacting 1,3-butadiene with hydrogen cyanide. The catalyst for the reaction of 1,3-butadiene with hydrogen cyanide to make 3-pentenenitrile is recycled. At least a portion of the recycled catalyst is purified by an extraction process, which separates catalyst degradation products and reaction byproducts, such as mononitriles having 9 carbon atoms, from the catalyst.
