Abstract: Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, as described herein. In particular, the present disclosure describes a process for the production of a nitrile intermediate by reacting a tetra-amino compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce the chelators at a high yield and/or a high purity.

Abstract: The present disclosure relates generally to processes for recovering tricyanohexane (TCH) via purification of by-product or co-product streams of adiponitrile production. In particular, the present disclosure relates to a process for purifying tricyanohexane (TCH), the process having the steps of (a) separating an adiponitrile process stream comprising adiponitrile and TCH to form a first overhead lights stream comprising low-boiling components and high-boiling components and a first bottoms heavies stream comprising high-boiling components and solid impurities; and (b) separating the first overhead lights stream in a distillation column to form a second overhead lights stream comprising low-boiling components, a second bottoms heavies stream comprising high-boiling components, and a TCH stream comprising TCH and less than 10 wt. % impurities; wherein the distillation column is a low pressure distillation column.
