  • Patent number: 11814337
    Abstract: A process for producing acetonitrile, the process comprising: treating a feedstock stream comprising methanol, allyl alcohol, oxazole, acetonitrile, water, and hydrogen cyanide to remove hydrogen cyanide and produce an acetonitrile stream comprising less than 1 wt. % hydrogen cyanide. The process further comprises the step of distilling the acetonitrile stream in a first distillation column to produce a first distillate comprising oxazole and methanol; a first intermediate acetonitrile stream comprising acetonitrile and oxazole and less than 1 wt % allyl alcohol; a first bottoms stream comprising allyl alcohol and water. The process further comprises the step of purifying the first intermediate acetonitrile stream to produce an acetonitrile product stream and a recycle stream comprising allyl alcohol.

  • Publication number: 20230192600
    Abstract: A process for producing acetonitrile, the process comprising dehydrating a feedstock stream comprising acetonitrile, acrylonitrile, allyl alcohol, and water (and optionally methanol) in a dehydration (first) column to yield a dehydrated acetonitrile stream comprising acetonitrile and acrylonitrile, less than 1 wt % allyl alcohol, and less than 50 wt % water, and optionally hydrogen cyanide; distilling the dehydrated acetonitrile stream in a lights (second) column to yield a distillate stream comprising lights, and a bottoms stream comprising acetonitrile, acrylonitrile, water, and optionally hydrogen cyanide and acrylonitrile; extracting the distillation bottoms stream in an extraction (third) column to yield a raffinate stream comprising acetonitrile and less than 200 ppm acrylonitrile and an extract stream comprising water and acrylonitrile; purifying the raffinate stream to yield a product acetonitrile stream.

  • Publication number: 20230008538
    Abstract: Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, with reduction of ammonia byproducts. In particular, the present disclosure describes a process for the production of a nitrile intermediate by reacting a tetra-amino compound or dinitrile compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce chelators at a high yield and/or a high purity.

    Abstract: In various embodiments, the present invention provides method of forming composites. Such methods generally comprise: (1) applying carbon nanotubes onto a system, wherein the system comprises at least one of an electric field or a magnetic field, and wherein the at least one electric field or magnetic field unidirectionally aligns the carbon nanotubes; and (2) applying a polymer onto the carbon nanotubes while the carbon nanotubes are unidirectionally aligned by the at least one electric field or magnetic field. The application of the polymer onto the carbon nanotubes forms composites that comprise unidirectionally aligned carbon nanotubes embedded in the polymer. In further embodiments, the present invention provides polymer composites formed by the methods of the present invention.
