Ammonium cyanate , NH ₄ OCN, is a chemical compound and the ammonia salt of cyanic acid .

history

By reacting ammonium cyanate to urea , Friedrich Wöhler succeeded for the first time in 1828 in producing a compound from both inorganic predecessor compounds and from animal or human products (urine), thus bridging the gap between organic and inorganic chemistry .

Extraction and presentation

Ammonium cyanate is produced by neutralizing ammonia with cyanic acid :

${\displaystyle \mathrm {NH_{3}+HOCN\longrightarrow NH_{4}OCN} }$

properties

Above 60 ° C, ammonium cyanate converts into urea .

${\displaystyle \mathrm {NH_{4}OCN\ {\xrightarrow {60\ ^{\circ }C}}\ H_{2}NCONH_{2}} }$
