Hydrolysis of organophosphate insecticides in aqueous media
Abstract Hydrolysis of crucron [0-(4-bromo-2-chorophenyl)-ethyl-s-n-propyl phosphorothioate], bromophos [0-(4-bromo-2,5-dichlorophenyl)0,0-dimethyl phosphorothioate] and fenitrothion [0,0-dimethyl-0-(4-nitro-m-tolyl phosphorothioate] was investigated in buffered aqueous media at various pH values. Rate constants and half-life studies revealed that these insecticides were relatively stable in acidic medium, and their stability decreased as the pH increased. The mode of decomposition of these compounds in acidic; the neutral medium is dealkylation which results in deakylated compounds and alcohols. In an alkaline medium they undergo hydrolysis resulting in the formation of phenol derivatives and dialkylphosphoric acid.
