Study of alkaline hydrolysis of the insecticide alphamethrine by isotachophoretic determination of decomposition products.
Alkaline hydrolysis of the pyrethroid insecticide alphamethrine has been studied. After hydrolytic cleavage at various temperatures and pH values, the degradation products, phenoxybenzoic acid and the dichloro derivative of chrysanthemic acid, were identified and determined by means of capillary isotachophoresis. Rate constants, activation energies and the reaction enthalpy and entropy were calculated.
