ABSTRACT:

Nucleophilic attack upon mono-4-chloro-3,5-dimethylphenylphosphate (4-CDMPP) and 4-chloro-3-methylphenylphosphate (4-CMPP) esters by OH- ions from NaOH in presence and absence of cetyltrimethylammoniumbromide (CTABr). The increase of the first order rate constants with the concentration of the surfactant can be analysed in terms of Br- ions in micellar pseudophase, which occur readily by aqueous CTABr and calculated second order rate constant.
