Sulfate radical-based oxidation of the aminopyralid and picloram herbicides: The role of amino group on pyridine ring

The widespread utilization of pesticides has attracted increasing attention to their environmental impacts and effective removal strategies. In the present study, the degradation of herbicides picloram (PCLO) and amino-pyralid (AMP) with similar structures were investigated systematically by thermo activated persulfate. Overweight SO4 center dot- was determined to be the predominant oxidizing species by quenching experiment. Obtained by laser-flash photolysis (LFP), reaction rate constants of SO4 center dot- towards AMP and PCLO were determined at 1.56 x 10(9) M-1 s(-1) and 1.21 x 10(9) M-1 s(-1), respectively. Product analysis revealed that both substances underwent similar oxidation paths, namely, successive oxidation on pyridine ring and formation of coupling-products as well as further hydroxylation and decarboxylation. Amino group on the pyridine ring was identified as the main reactive site, which was further confirmed by DFT calculation. It was susceptible attacked by SO4 center dot- to form deamination, nitration, and self-coupling products. These couples could be further oxidatively dehydrated to form azo and a series of azo derivatives. EOCSAR program predicted significant hazards on aquatic species during the formation of these couplings and azo derivatives. Our work emphasized the potential ability and toxicity of contaminates to produce azo substances in the presence of amino groups on the pyridine ring.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 175358-01-7 is helpful to your research. Quality Control of 3-Amino-6-chloropicolinamide.

Molecular Weight Effect on the Transition Processes of a Symmetric PS-b-P2VP during Spin-Coating

We studied the morphological transition behaviors in symmetric poly(styrene-b-2-vinyl pyridine) (PS-b-P2VP) with different molecular weights during spin-coating from a toluene solution using grazing-incidence small-angle X-ray scattering (GISAXS). For the lowest molecular weight condition used here (the number-average molecular weight, M-n, was 16,500), the disordered micelles transitioned into disordered structures during evaporation. When M-n = 50,000, the micelles transitioned into hexagonally packed cylindrical structures parallel to the substrate and then into lamellar structures. The effect of selective solvent evaporation on the transition process became significant when Mn was larger than 84,000. For M-n = 84,000 and 199,000, the micelles first transitioned into spheres on the body-centered cubic lattice (BCC), where the BCC (110) plane was aligned perpendicular to the substrate. Then, the spheres coalesced into loosely packed cylindrical structures. The convection effect of the solvent caused this coalescence, and vitrification prohibited continued transitioning into the lamellar structures from the cylindrical structures. PS-b-P2VP with M-n = 428,000 self-assembled into loosely packed cylindrical structures perpendicular to the substrate; thin films were formed after the transition from micelles into BCC structures. However, the BCC (110) plane did not become aligned perpendicular to the substrate because a large amount of solvent contained in the PS component prevented alignment due to convection during the selective solvent evaporation.
