The present contribution reports on the analysis of the high resolution FTIR spectra of the only two IR-active parallel fundamentals v u and v12 of the isotopomers 1 2 C 3 1 4 N 3 H 3 , 1 3 C 3 1 4 N 3 H 3 , 1 2 C 3 1 5 N 3 H 3 , C 3 1 5 N 3 H 3 and 1 2 C 3 1 4 N 3 D 3 , respectively, of 1,3,5-triazine. The molecular constants of the ground state and the upper states u u = l and vl2 = \, respec...

We have used thermospray LC-MS to confirm three highly polar metabolites (A, B. and G) of the herbicide hexazinone [3-cyclohexyl-6-(dimethylamino)-l-methy~-1,3.S-triazine-2,4( lH,3H)-dione]. and chemical ionization GC-MS to confirm two other metabolites (D and E) in extracts of soil and vegetation from a forest in the Central Alabama Piedmont. Selected-ion monitoring (SIM) of the protonated mol...

Triazine and chloroacetanilide concentrations in rainfall samples collected from a 23-state region of the United States were analyzed with microtiter-plate enzyme-linked immunosorbent assay (ELISA). Thirty-six percent of rainfall samples (2072 out of 5691) were confirmed using gas chromatography/mass spectrometry (GC/MS) to evaluate the operating performance of ELISA as a screening test. Compar...

Hydrolysis of cyanuric acid, melamine, melem, atrazine and melamine-formaldehyde resin was found to be catalyzed by an A1203 catalyst. The reactions occur irreversibly with cleavage of the s-triazine ring between 240 and 450°C. The s-triazine-ring is hydrolyzed to ammonia and carbon dioxide, and the substituted groups to the corresponding molecules by addition of hydrogen.

A new triazine functionalized hexagonally ordered covalent organic polymer (TRITER-1) has been synthesized via the Schiff-base condensation reaction between a tailor made triamine 1,3,5-tris-(4-aminophenyl)triazine (TAPT) and terephthaldehyde. This ordered porous polymer showed a high BET surface area (716 m(2) g(-1)) and an excellent CO2 uptake capacity of 58.9 wt% at 273 K under 5 bar pressure.

Triazine derivatives, namely, 2,4,6-tris(quinolin-8-yloxy)-1,3,5-triazine (T3Q), N²,N⁴,N⁶-tris(pyridin-2-ylmethyl)-1,3,5-triazine-2,4,6-triamine (T3AMPy) and 2,2',2''-[(1,3,5-triazine-2,4,6-triyl)tris(azanediyl)] tris(ethan-1-ol) (T3EA) were synthesized and their inhibition of steel corrosion in hydrochloric acid solution was investigated using electrochemical techniques. The corrosion protecti...

BACKGROUND Atrazine and other triazine herbicides are widely used in US maize and sorghum production, yet the most recent market-level assessment of the economic benefits of atrazine is for market conditions prevalent in the early 1990s, before commercialization of transgenic crops. Grain markets have changed substantially since that time; for example, the size of the US maize market increased ...

UTAGENESIS in germ cells of Drosophila melanogaster males by 2: 4: 6-tri M (ethyleneimin0)-1 : 3 : 5-triazine (“triazine”) has been proven and investigated by the FAHMY’S (BIRD 1952; FAHMY and BIRD 1953; FAHMY and FAHMY 1953, 1954, 1955) and has also been studied by LUERS (1953). The purposes of the present studies were to test whether triazine, like nitrogen mustard (HERSKOWITZ 1947, 1949, 195...

Pesticides based on the s-triazine ring structure are widely used in cultivation of food crops. Cleavage of the s-triazine ring is an important step in the mineralization of s-triazine compounds and hence in their complete removal from the environment. Cyanuric acid amidohydrolase cleaves cyanuric acid (2,4,6-trihydroxy-s-triazine), which yields carbon dioxide and biuret; the biuret is subject ...
