Melam (N2-(4,6-diamino-1,3,5-triazin-2-yl)-1,3,5-triazine-2,4,6-triamine) 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.
