    Abstract: A process for producing a partially balanced acid solution that involves metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder at a low variability feed rate into an in-line disperser, adding a first feed stream of diamine to the in-line disperser in an amount sufficient to form the partially balanced acid solution having a solids content of less than 60%, and storing the partially balanced acid solution at a temperature to maintain the dissolved dicarboxylic acid and to prevent formation of a slurry. The partially balanced acid solution may be used as a feed solution to prepare a nylon salt solution. Process controls for the process are also disclosed.

    Abstract: A solvent is at least partially separated from a catalyst. The catalyst comprises nickel and a bidentate phosphorus-containing ligand. The method for separation involves distilling a catalyst solution. The ratio of 2-pentenenitrile to 3-pentenenitrile in distillation column bottoms is controlled to reduce the amount of 3-pentenenitrile which is isomerized to form 2-methyl-3-butenenitrile. Isomerization of 3-pentenenitrile to 2-methyl-3-butenenitrile and subsequent isomerization of 2-methyl-3-butenenitrile to 2-methyl-2-butenenitrile, and/or hydrocyanation of 2-methyl-3-butenenitrile to methylglutaronitrile represents a loss in adiponitrile yield in a process for making adiponitrile.

    Abstract: Described is a process for the integrated production of hexamethylenediamine. The process includes integrating an HCN production process, a dinitrile compound production process, and a diamine production process. The HCN production process provides HCN for hydrocyanating butadiene to form a dinitrile compound and a hydrogen stream for hydrogenating the dinitrile compound to form a diamine. The HCN production process includes forming a crude hydrogen cyanide product and separating the crude hydrogen cyanide product to form an off-gas stream and a hydrogen cyanide product stream. The off-gas stream is further separated to recover hydrogen. The hydrogen cyanide product stream is further processed to recover hydrogen cyanide.
