Abstract: In the recovery and purification of acrylonitrile or methacrylonitrile obtained by the ammoxidation of propylene or isobutylene, the aqueous layer of the decanter associated with the column removing HCN from the nitrile is recycled to the quench column wherein the hot gases from the reactor are directly contacted with the aqueous recycle stream.

Abstract: The present invention provides a method for greatly reducing the amount of solids-containing waste streams produced during the recovery of acrylonitrile or methacrylonitrile produced by the ammoxidation reaction of propylene or isobutylene with molecular oxygen and ammonia. … This is realized by recycling at least a part of the product column bottoms to the quench column.
