NH4OCN - AMMONIUM CYANATE

Properties of ammonium cyanate:

White, with gentle heating isomerizes to carbamide. It is readily soluble in cold water (hydrolysis on cation and anion). Decomposes by hot water, acids, alkalis. Oxidized by nitrous acid and sodium hypochlorite. Participates in reactions of an exchange and complex formation.


Molar mass g/mol 60.06

Methods for preparation of ammonium cyanate:

AgOCN + NH4Cl = AgCl↓ + NH4OCN.


Chemical reactions with ammonium cyanate:

NH4OCN = (60° C) = C(NH2)2O(carbamide).

C(NH2)2O(carbamide) = (160-190° C, vacuum) = NH4OCN.

NH4OCN(diluted, cold) = NH4(+) + OCN(-),

NH4(+) + 2H2O = NH3 • H2O + H3O(+),

OCN(-) + H2O = HOCN + OH(-).

NH4OCN(conc., hot) = C(NH2)2O.

NH4OCN + HCl(conc.) = HOCN + NH4Cl (normal temp.).

NH4OCN + 2NaOH(conc.) = 2NH3↑ + Na2CO3 (boiling).

NH4OCN + 2HNO2(conc.) = time = 2N2↑ + CO2↑ + 3H2O.

NH4OCN + 3NaClO = N2↑ + 3NaCl + CO2↑ + 2H2O (boiling).

NH4OCN + AgNO3 = AgOCN↓ + NH4NO3,

2AgOCN + I2 = 2AgI + (NCO)2 (0° C, in liquid CCl4).
