Abstract
1,135,712. Production of ammonium nitrite. GOSUDARSTVENNY NAUCHNO ISSLEDOVATELSKY I PROEKTNY INSTITUT AZOTNOI PROMYSHLENNOSTI I PRODUKTOV ORGANICHESKOGO SINTEZA. 6 Feb., 1967, No. 5571/67. Heading C1A. Ammonium nitrite is prepared by reacting nitric oxides with ammonium carbonate solution, at a pressure of 2 to 7 atmos. Nitrous gases obtained by the catalytic oxidation of ammonia under a pressure of 2 to 7 atmos. pass respectively through a cooler, a scrubbing tower (where the extent of oxidation of the nitrous gases is adjusted by the partial removal of nitrogen dioxide by dil. nitric acid circulating the tower), a brine cooler (where water and acid vapours present in the nitrous gases condense) and finally to an absorption column where partial oxidation occurs and the oxidized gases react with ammonium carbonate solution, in countercurrent under a pressure of 2 to 7 atmos.
