Dehydration of ammonium carbamate produces:
Dehydration of ammonium carbamate produces:
Open in App
Solution
The correct option is D urea
The ability of ammonium
carbamate to make urea was first discovered in 1870 by Bassarov when he heated
ammonium carbamate in sealed glass tubes at temperatures ranging from 130 to
140 ℃. This yields urea and water in an equimolar ratio. A typical industrial plant that makes urea can
produce up to 1500 tons a day. Ammonia and carbon dioxide is excessively fed to
a synthesis reactor in this process. Ammonium carbamate is produced as an
intermediate in this reactor and can then be dehydrated to urea according to
the following equation.
H2N−COONH4→NH2CONH2+H2O
