Abstract: Acrylonitrile or methacrylonitrile was manufd. by the ammoxidn. of propylene or isobutylene and recovered from the reaction mixt. by contacting the product stream with a guenching liq. which forms a gaseous stream, absorbing the gas in water to form a soln. and distg. the soln. to recover acetonitrile by removing the major part of the byproduct and water. The bottom flow from the distn. column is recycled and used at least a part of the quenching liq.

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.
