Nonbiological detoxication of the s-triazine herbicides
1970Until recently, microbial decomposition was considered the main pathway for detoxication of the s-triazine herbicides in soils. Organisms have been isolated which can detoxify these herbicides (Kaufman et al. 1965). Factors such as temperature and soil organic matter which influence soil microbial activity have been shown to correlate with the rate of ...

s-Triazine derivatives. 3. Investigation of the reaction of chloromethoxy-s-triazines with CH acids
Chemistry of Heterocyclic Compounds, 1981The condensation of 2-chloro-4,6-dimethoxy- and 2,4-dichloro-6-methoxy-s-triazines with sodium derivatives of ethyl esters of acetoacetic and cyanoacetic acids and malonodinitrile was investigated. 2-Dicyanomethylene-4,6-dimethoxy-1,2-dihydro-, 2-carbethoxycyanomethylene-4,6-dimethoxy-1,2-dihydro-, and 2,4-bis(carbethoxy-methylene)-6-methoxy-1,2,3,4 ...

Abstract The inelastics neutron scattering (INS) spectra of s-triazine and trichloro-s-triazine at 5 K provide the first observation of the IR and Raman inactive modes, v 4 and v 5 . A full assingment is made by fitting a harmonic force field to the INS spectra profile. In the case of trichloro-s-triazine we demonstrate that this approach can be

Phosphorescence of s-triazine vapor
Chemical Physics Letters, 1983Abstract The phosphorescence of s-triazine vapor has been observed by means of time-resolved emission spectroscopy. The phosphorescence spectrum is diffuse with a faint vibronic structure in the shorter-wavelength region. The phosphorescence quantum yield is 3.0 × 10−5 for excitation at the 620 absorption band of the S0 → S1 transition, and the ...

Conformation of triphenyl-s-triazine
Journal of the Chemical Society, Perkin Transactions 2, 1977The infinite dilution molar Kerr constant of triphenyl-s-triazine as a solute in dioxan at 298 K is analysed to provide evidence concerning the molecular conformation. Structures having equivalent rotations of the phenyl groups about the inter-ring bonds are considered and its is found that the dihedral angle, ϕ, lies within the range 0 ⩽ϕ⩽ 27°.

Movement of s-triazine herbicides in soils
1970The movement of an organic pesticide1 placed onto or within the soil may influence both its effectiveness and its potential as a contaminant in adjacent soil, water, or air. Movement may occur while in solution or adsorbed on migrating soil particles, or by transfer as vapors.

Montmorillonite — S‐Triazine Interactions
Israel Journal of Chemistry, 1968AbstractAdsorption of s‐triazines on montmorillonite surfaces results in hydrolysis and protonation of the s‐triazine compounds. Infrared studies suggest that dissociation of adsorbed water on the clay surface plays a major role in protonation and hydrolysis of the s‐triazine herbicides.

Nature, 1957
IN the course of investigations on s-triazines, we have discovered a new synthesis of 2-alkoxy- and 2-alkylthio-4,6-dichloro-s-triazines. These substances can be obtained by the reaction of an alcohol or a thiol with cyanuric chloride and 2,6 x collidine as the acid acceptor. The yield was approximately 80–90 per cent.

Liquid chromatography of the s-triazines
Chromatographia, 1981A series of thirty s-triazine compounds have been separated using reversed-phase high-pressure liquid chromatography. A relationship between substituent activity and retention time was developed to predict molecular structure.
