Trifluralin: Photolysis under sunlight conditions and reaction with HO{radical dot} radicals

The gas phase atmospheric degradation of trifluralin (a widely used herbicide) has been investigated at the EUPHORE facility. Its photolysis has been studied under sunlight conditions and its reaction rate constant with HO{radical dot} radicals was measured using the relative rate method. Using 1,3,5-trimethylbenzene as reference compound, the rate constant of HO{radical dot} reaction with trifluralin was obtained to be kHO{radical dot} = (1.7 ± 0.4) × 10- 11 cm3 molecule s-1 at (300 ± 5) K and atmospheric pressure. The mean photolysis rate measured under solar radiation was Jtrifluralin = (1.2 ± 0.5) × 10-3 s-1(JNO2 = 8 × 10- 3 s- 1) . The photolysis of trifluralin was found to generate organic aerosols with a yield of (20 ± 10)%. The data obtained enabled us to discuss the atmospheric fate of trifluralin in the gas phase.

19F NMR as an Analytical Tool for Fluorinated Agrochemical Research

19F NMR was utilized to monitor the photodegradation of trifluralin directly in NMR tubes without extraction, cleanup, concentration, or chromatographic separation.Dissipation curves were generated for the parent pesticide and degradation products, and the major products identified by addition of authentic standarts were α-α-α-trifluoro-2,6-dinitro-N-propyl-p-toluidine (II), α,α,α-trifluoro-2,6-dinitro-p-toluidine (III), and 2-ethyl-7-nitro-5-(trifluoromethyl)benzimidazole (VII).Numerous peaks were observed in the spectra that may represent labile intermediates not generally observed with other analytical techniques.Keywords: 19F NMR; trifluralin; photodegradation
