    Abstract: 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.

    Abstract: Disclosed are processes for applying dyes, stain blocker and anti-soil compositions on BCF yarns during cable or air twisting processes, or heat setting processes, prior to weaving, knitting or tufting. Further discloses are process for applying dyes, stain blocker and anti-soil compositions on BCF yarns prior to heat setting. The processes forego the need to dye and otherwise treat carpets and other textiles made from the BCF yarn using current methods. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed process.

    Abstract: A method is disclosed for removing contaminants from a feed stream to a hydrogenation process that begins with providing a product mixture from an air oxidation reaction. A first liquid separation process and cooling procedure is used on the product mixture to form a cooled product mixture and a first vapor stream. The cooled product mixture is then subjected to a water wash to form a washed product mixture and an aqueous exit stream, wherein a majority of the water soluble other oxidation products from the cooled product mixture are present in the aqueous exit stream. Next, the washed product stream undergoes a second liquid separation and water removal to form a treated product mixture and a second vapor stream. Finally, the treated product mixture is recovered and can be fed to a hydrogenation process.
