Micellar Effects upon Dephosphorylation in Water and Aqueous 1,2-Diols

Cationic micelles of cetyltrimethylammonium bromide and chloride (CTABr and CTACl) in aqueous ethane- and propane-1,2-diol speed reaction of OH^- with p-nitrophenyl diphenyl phosphate (pNPDPP).Reaction with F^- was examined in aqueous ethane-1,2-diol.The rate-surfactant profiles have been treated quantitatively by use of the ion-exchange pseudophase model and, for reaction with OH^-, direct comparison has been made with the profile for reaction in aqueous CTABr.Reaction with OH^- in aqueous CTABr has also been treated quantitatively by use of a mass-action model, and the conclusions of the two treatments are compared.The functional surfactant, N,N-dimethyl-N-(2-hydroxyethyl)-N-hexadecylammonium bromide is an effective dephosphorylating agent in aqueous ethanediol containing NaOH.
