싸이오사이안산암모늄(로단암몬)

용도Colorless deliquescent crystals made by boiling an aqueous solution of ammonium cyanide with sulfur or polysulfides. It must be kept in a well-sealed container. The principal use for ammonium thiocyanate was in gold-toning formulas, but it was also used in a 5 percent solution to dissolve gelatin in overexposed carbon prints.

일반 설명Ammonium thiocyanate is a colorless crystalline solid. Ammonium thiocyanate is soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium thiocyanate is used in chemical analysis, in photography, as a fertilizer, and for many other uses.

(NH4)2S is obtained from reacting hydrogen sulfide with excess of ammonia:H2S + 2NH3 → (NH4)2S.

생산 방법Ammonium thiocyanate (plus ammonium sulfide) [CAS: 12135-76-1] may be made by reaction of ammonia and carbon disulfide, a reaction which probably accounts for the presence of ammonium thiocyanate in the products of the destructive distillation of coal. This reaction corresponds to the formation of ammonium cyanate from ammonia and carbon dioxide.

정의ammonium thiocyanate: A colourless, soluble crystalline compound,NH4NCS. It is made by theaction of hydrogen cyanide on ammoniumsulphide or from ammoniaand carbon disulphide in ethanol. Onheating, it turns into its isomerthiourea, SC(NH2)2. Its solutions givea characteristic blood-red colour withiron(III) compounds and so are employedas a test for ferric iron. Ammoniumthiocyanate is used as arapid fixative in photography and asan ingredient in making explosives.
