(United States of America). CODEN: USXXAM. CLASS: IC: C07D251-36. NCL: 260242000. PRIORITY: ES 73-420561 15 Nov 1973. DOCUMENT TYPE: Patent CA Section: 61 (Water) Dichlorocyanurate silver complexes of the formulas Ag1A1Z2 and Ag2B1Z4 where Z is the dichlorocyanurate radical (C3N3O2Cl2)-, A is an alkali metal and B is an alk. 2244-21-5 and 61113-41-5 are cas registry numbers of chemicals which are used as reagents here. earth metal, are bactericides, fungicides and algicides. They are highly stable, have a low solubility in water, and are suitable for use in cooling towers, paper manufg. waters, etc. Thus, silver potassium dichlorocyanurate [61113-41-5] was prepd. by mixing 9.4 g potassium dichlorocyanurate [2244-21-5] in 200 ml water and 3.4 g AgNO3 [7761-88-8] in 100 ml water. .

Decreasing nitrogen oxide generation in silver nitrate manufacture

Decreasing nitrogen oxide generation in silver nitrate manufacture. Hanaoka, Toshikazu; Tozawa, Katsutoshi (Konishiroku Photo Industry Co., Ltd., Japan). Japan. Kokai JP 51060676 26 May 1976 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C02C005-04. APPLICATION: JP 74-135737 25 Nov 1974. DOCUMENT TYPE: Patent CA Section: 59 (Air Pollution and Industrial Hygiene) O is blown into a reaction mixt. which generates NOx, to decrease the NOx generation. The process is esp. useful for preventing or decreasing NOx generation from a Ag-HNO3 reaction mixt. for making AgNO3 [7761-88-8] in the photog. industry. Thus, granular Ag 140 g and 61% HNO3 25 ml were charged into a flask, and O was fed into the mixt. through a nozzle at 200 ml/min while 75 ml 61% HNO3 was added dropwise. Ag dissoln. and amt. of NOx generated were 127.2 g and 0.15 mole (as NO), resp., compared to 107.9 g and 0.33 mole when no O was fed.
