WebJun 1, 2024 · Triazines are formed through the reaction between an alkanolamine and formaldehyde, where the most common triazine is monoethanolamine-triazine, or MEA … Triazines are a class of nitrogen-containing heterocycles. The parent molecules' molecular formula is C3H3N3. They exist in three isomeric forms, 1,3,5-triazines being common. See more The triazines have planar six-membered benzene-like ring but with three carbons replaced by nitrogens. The three isomers of triazine are distinguished by the positions of their nitrogen atoms, and are referred to as 1,2,3 … See more Melamine A well known triazine is melamine (2,4,6-triamino-1,3,5-triazine). With three amino substituents, melamine is a precursor to commercial resins. Guanamines are closely related to melamine, except with one amino substituent … See more • Hexahydro-1,3,5-triazine • 6-membered rings with one nitrogen atom: pyridine • 6-membered rings with two nitrogen atoms: diazines See more The more common 1,3,5-isomers are prepared by trimerization of nitrile and cyanide compounds, although more specialized methods are known.
