Kinetics of the reaction of methyl 4-nitrobenzenesulfonate + Br- in ethanol amine based surfactants

The kinetics of the reaction of methyl 4-nitrobenzenesulfonate + Br - ions has been studied in ethanol amine based (alkyldimethylethanolammonium bromide and alkyldiethylethanolammonium bromide) surfactant solutions. The observed first-order rate constants increase monotonically with surfactant concentration, with hydrophobic chain length and with head group bulk in a manner similar to other quaternary ammonium surfactants. The results were analyzed using the pseudophase model of micellar rate effects in conjunction with a Langmuir form to describe micellar binding of bromide ion. An attempt to estimate activation parameters of the reaction from temperature variance of micellar pseudophase rate constants has also been made.

Micellar Effects upon the Rates of SN2 Reactions of Halide Ions

Observed first-order rate constants for reactions of Cl- or Br- with alkyl benzenesulfonate (1a-c) in micelles of cetyltrimethylammonium surfactants (CTAX, X=Cl, Br, OMes, 0.5SO4) increase monotonically with increasing or or halide ion concentration and tend to limiting values.In CTAOMes or (CTA)2SO4, the rate constants go through maxima.The variation of the rate constants with concentrations of surfactant and halide ion can be fitted to an equation that accounts for the distribution of both reactants between water and micelles, i. e., in terms of ion-exchange and mass-action models.The second-order rate constants in the aqueous and micellar pseudophases are similar.
