摘要： Nickel-metal-containing solids for use in manufacturing nickel metal complexes are disclosed. The nickel-metal-containing solids are made by reducing basic nickel carbonates. By varying the molar ratios of carbonates and bicarbonates to nickel salts, the methods provide basic nickel carbonates that produce superior nickel metal-containing solids that react more effectively with phosphorous-containing ligands. The phosphorous containing ligands can be both monodentate and bidentate phosphorous-containing ligands.

摘要： A continuous process for producing a nylon salt solution prepared using a liquid partially balanced acid solution enriched in dicarboxylic acid, and in particular adipic acid. The liquid feed is prepared by metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder into an in-line disperser; feeding a first feed stream of diamine to the in-line disperser to form a dispersion comprising between 32 wt. % and 46 wt. % dicarboxylic acid, between 11 wt. % and 15 wt. % diamine, and between 39 wt. % and 57 wt. % water, and heating the dispersion at temperature between 50 C and 60 C to form a partially balanced acid solution. A nylon salt solution is prepared from the liquid partially balanced acid solution and continuously withdrawn into a storage tank. The nylon salt solution has a uniform pH and is suitable for producing nylon polymers.

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 NiL2A type wherein L2 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.
