Photolysis of the fungicide flutolanil, 3'-isopropoxy-2-(trifluoromethyl)benzanilide, was investigated both in an aqueous solution and on solid surfaces (silica gel and glass) by irradiating with UV light under laboratory conditions.In an ethanolic aqueous solution, irradiation resulted in the formation of a major product and some other products .The latter is considered to have been formed by the reaction with an organic solvent.On the solid surfaces, the main photoproduct was 2'-amino-4'-isopropoxyphenyl 2-(trifluoromethyl)phenyl ketone, a product from the photo-Fries rearrangement reaction.Another photoproduct, 3'-hydroxy-2-(trifluoromethyl)benzanilide was obtained only on the glass surface, this desisopropylated compound not being detected under any other conditions.The photolysis of this fungicide, was accelerated more by carbonyl compounds such as benzophenone, acetophenone, flavone and xanthone than by dye photosensitizers like rose bengal, chlorophyllin and riboflavin.
