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.

Abstract: A process for producing an intermediate adiponitrile stream, the process comprising separating an adiponitrile process stream comprising less than 50 wt % adiponitrile, and optionally TCH, to form the intermediate adiponitrile stream comprising at least 5 wt % adiponitrile and a heavies stream comprising high-boiling components and optionally solid impurities; and optionally utilizing at least a portion of the intermediate adiponitrile stream outside of the process.
