Abstract: Provided herein are processes for purifying TCH in a feed stream, such as an adiponitrile process stream. The processes include a first separating step of separating the adiponitrile process stream to form a first overhead stream comprising low-boiling components and high-boiling components and a first bottoms stream comprising high-boiling components. The processes also include a second separating step of separating the first overhead stream in one or more distillation columns to form a lights stream comprising low-boiling components, a heavies stream comprising high-boiling components, and a TCH stream.

Abstract: A nanofiber nonwoven product is disclosed which comprises a polyamide with a relative viscosity from 2 to 330, spun into nanofibers with an average diameter of less than 1000 nanometers (1 micron). In general, the inventive products are prepared by: (a) providing a polyamide composition, wherein the polyamide has a relative viscosity from 2 to 330; (b) melt spinning the polyamide composition into a plurality of nanofibers having an average fiber diameter of less than 1 micron, followed by (c) forming the nanofibers into the product.

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.
