Melam (chemistry)


Melam is a condensation product of melamine.

Synthesis

Melam was discovered by Liebig in 1834 from the residue of heating ammonium thiocyanate.

Chemical property

In the presence of 30% ammonia, melam undergoes hydrolysis to form ammeline and melamine. It also reacts with concentrated nitric acid, producing cyanuric acid.
Upon heating, melam first loses ammonia to form melem, and then melon.
