ABSTRACT:

Hydrolysis of Ethyl-cyanophos (organophosphorus compounds) has been studied in acidic medium with catalysts such as Zr4+, Ce4+, Hf4+ and Th4+ cations and the rate maxima observed were at around pH 2.0. Since the metal aquo complexes are known to exist in equilibrium with deprotonated species and therefore, metal bound OH- nucleophile might be available abundantly even in acidic aqueous solutions. Thus an interaction of sulphur of P=S group with metal cation followed by an intramolecular nucleophilic attack of hydroxy anion at the ester phosphorus atom would results in cleavage of P-O bond.
