VII. A Simple Model System Hydrolysis of Some Cardamate Pesticides

摘要

The decomposition of the carbamate insecticides carbaryl and Mobam and the herbicides IPC and CIPC in water at various pH's was investigated. Analyses were performedin situon silica-gel thin-layer chromatograms by reflectance spectroscopy after the developed chromatograms had been sprayed with the reagent CNTNF (9-dicyanomethylene-2,4,7-, trinitrofluorene) to form visible pi-complexes of the pesticides. Carbaryl and Mobam decomposed rapidly at basic pH's but were stable in acid. IPC and CIPC were stable in water at pH's tested.
