The hydrolysis reaction of parathion (PTH) to produce para-nitrophenolate (pNP) and O,O-diethylthiophosphate (DETP) was examined in a minimally disturbed liquid-liquid biphasic reaction system by proton and phosphorous nuclear magnetic resonance spectroscopy. The effect of the micellar cationic surfactant, cetyltrimethylammonium chloride (CTAC), on PTH transport, hydrolysis, and system characteristics including reactant-product concentrations, pNP partition coefficients, pNP surface activity, ultraviolet degradation of pNP, oxidation of pNP, and impurities in PTH are reported. Surfactant reaction systems resulted in a 2.5 order of magnitude increase in the amount of PTH transported into the aqueous layer as compared to the control system at 2100 …
