TRIAZINES, in organic chemistry, a series of cyclic compounds, containing a ring system composed of three carbon and three nitrogen atoms. Three series are possible, the positions of Marine Trias Of The Alpine And Indian Types.
C02-}-NH3 the various units of the ring system being illustrated in the annexed formulae: C C C NI^C CI C N/ C A N ` N' N C,C N N N a-Triazines, (-Triazines, Cyanidines.

Harries (Ber., 1895, 28, p. 1223) has also shown that as-phenylhydrazino-acetic esters, when heated with formamide and substituted formamides under pressure, yield dihydrotriazines: CO 2 R CO-NR'-CH H2 N(C6H5)NH2 +R'NH CHO --> CH 2 N(C 6 H 5) IV The phen-a-triazines are yellow-coloured crystalline compounds of a somewhat basic character.
Derivatives of triazines are formed by the action of nitrous acid on ortho-aminobenzylamines (M.
