Abstract/Description
-
The photodegradation of propiconazole (1-{[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl}-1 H-1,2,4-triazole), a systemic fungicide, by ultraviolet radiation has been studied. After 12 hours of continuous irradiation, propiconazole undergoes degradation in aqueous solution. The process requires the presence of oxygen and continuous agitation. Similarly, propiconazole undergoes degradation in organic solvents as well (methanol, hexane)., Four photoproducts were detected and...

After 12 hours of continuous irradiation, propiconazole undergoes degradation in aqueous solution. The process requires the presence of oxygen and continuous agitation. Similarly, propiconazole undergoes degradation in organic solvents as well (methanol, hexane)., Four photoproducts were detected and identified and one of them was isolated. The dioxolan ring is the structure susceptible to the cleavage in the irradiation process.*, *Please refer to dissertation for diagram.
