CPC classification number: C07C253/34

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.
