Influence de l'acetophenone sur la photostabilite des formulations: cas du carbetamide formule.

Acetophenon is a solvent which is very often used in the formulation of pesticides. When we study the photodegradation of Carbetamide in presence of Acetophenone we get an enhancement of the kinetic and the formation of a new compound. This new compound becomes from a Fries rearrangement and is the result of a triplet transfer between Acetophenon and Carbetamide

Photodegration of Pesticides - VII Photodegration of Carbetamide - Photoproducts.

The Photochemical degradation of the herbicide Carbetamide in different solvents has been investigated. The photoproducts were characterised by spectroscopic methods and also identified by comparison with synthetic samples. The pathway of formation of the photoproducts is described

Factors determining the behaviour and transformation of selected pesticides in water, soil suspension and soil.

The lifetimes of organic chemicals in the environment are determined by chemical processes. Photochemical degradation of Gardona, Atrazine, Diazinon, Parathion, Phenmedipham, Carbetamide and Carbofuran have been studied in distilled water, river water, in soil suspension and adsorbed on soil
