    Abstract: An antimicrobial conveyor belt apparatus comprising multiple segments each having a body portion and interlocking fingers extending from the body portion. The segments comprise a polymer composition comprising from 50 wt. % to 99.9 wt. % of a polymer, from 0.01 wt % to 10 wt % zinc, optionally from a zinc compound, less than 1 wt % of a phosphorus compound, and from 0 wt % to 20 wt % molding additives. The conveyor belt apparatus (or the segments thereof) demonstrates a Staphylococcus aureus log reduction greater than 1.0, as determined via ISO 22196:2011.

    IPC: C07C253/34

    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 terpolymer composition is described that contains a statistical amount of 50-98 wt % of a first repeating AA-BB comonomer unit; 1-25 wt % of a second repeating AA-BB comonomer unit; and 1-25 wt % of a repeating lactam comonomer unit or 1-25 wt % of a third repeating AA-BB comonomer unit, where the terpolymer composition exhibits a high melting point similar to that of PA66 while also exhibiting a significantly reduced crystallization rate and crystallization temperature.

    Abstract: The present disclosure relates to a process for stabilizing an antimony ammoxidation catalyst in an ammoxidation process. The process may comprise providing an antimony ammoxidation catalyst to a reactor; reacting propylene with ammonia and oxygen in the fluidized bed reactor in the presence of the antimony ammoxidation catalyst to form a crude acrylonitrile product; and adding an effective amount of an antimony-containing compound to the antimony ammoxidation catalyst to maintain catalyst conversion and selectivity; wherein the antimony-containing compound has a melting point less than 375° C. The present disclosure also relates to catalyst compositions and additional processes using the antimony ammoxidation catalyst stabilized by an antimony-containing compound.
