Abstract: The method can be applied for the extraction of the nonreacted ammonia from the outlet reactor flow produced by the reaction zone used for the production of acrylonitrile or methacrylonitrile. According to the method the outlet flow is cooled by aqueous solution of ammonium phosphate where the ratio between the ammonium and the phosphate ions is 0.7:1.3, preferably around 0.9-1.2. 18 claims, 2 figures
