Abstract: Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, are 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 to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt % to 30 wt %, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.

Abstract: A process for producing a high-purity acetonitrile product from a low-purity acetonitrile feedstock streams. In particular, the present disclosure relates to a process for producing a sales-grade, high purity acetonitrile by (a) distilling the feedstock stream in a to yield a crude acetonitrile stream, (b) treating the crude acetonitrile stream to produce an intermediate acetonitrile stream, (c) purifying the intermediate acetonitrile stream in a pressure swing distillation system to produce a recycle stream and an acetonitrile product stream, (d) recycling the recycle stream to the first distillation column, and (e) distilling the acetonitrile product stream to yield a purified acetonitrile product stream of at least 98 wt. % acetonitrile.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.
