Transformation of Z-thiacloprid by three advanced oxidation processes: Kinetics, intermediates and the role of reactive species

Three advanced oxidation processes (AOPs), heterogeneous photocatalysis, vacuum ultraviolet (VUV) photolysis and γ radiolysis were used for the generation of reactive primary free radicals to induce the transformation of Z-thiacloprid in aqueous solution. The effects of dissolved oxygen and the initial concentration (from 10?6to 10?4?mol?L?1) were investigated. The initial reaction rates increased with the initial concentration of thiacloprid, both in oxygen saturated and oxygen free solutions. Dissolved oxygen had significant effect on the transformation rate only in case of heterogeneous photocatalysis. Three main intermediates and the E-thiachloprid were detected using all three methods. One of these intermediates could be related to the reaction with eaq?, while the other two could be related to the [rad]OH-initiated reactions. Heterogeneous photocatalysis showed the highest efficiency regarding the transformation of intermediates in presence of dissolved oxygen, while thiacloprid transformed with the highest initial reaction rate during VUV photolysis. However, according to the Electric energy per order (EEO) data γ radiolysis was found to be the economically most feasible method, requiring several orders of magnitude less energy than VUV photolysis and heterogeneous photocatalysis for reduction of the target compound concentration by one order of magnitude in a unit volume.

Novel synthesis method of thiacloprid

The invention discloses a novel synthesis method of thiacloprid. The novel synthesis method includes: mixing raw materials including 2-cynaoimido-1, 3-thiazolidine and 2-chloro-5-chloromethylpyridinein a solvent, allowing reaction in a condition of guanidine organic alkali, and adopting different aftertreatment methods according to different solvents. Guanidine is adopted as an acid binding agent, and reaction temperature is moderate, so that compared with existing high-temperature processes, energy consumption is saved; guanidine hydrochloride is readily soluble in water and organic solventand simple in aftertreatment, high-purity thiachloprid of higher than 97% in content can be obtained by only adding a little water (and alcohol), and the method is suitable for large-scale industrialproduction; by adopting the novel synthesis method, product yield can reach higher than 92%; guanidine in wastewater can be further recycled after the organic solvent is recycled, so that production cost is lowered; only a little saline is generated finally, so that requirements on environment-friendly production are met.
