Correlation of Kinetic and Rheological Data for Flexible Nanoparticle Catalysis in the Reaction of Piperidine with PS −

The effect of apparent catalysis at different concentration of flexible nanoparticles (FN), (FN = CTABr|MX|H 2 O) of piperidine with phenyl salicylate ion when substituted sodium phenolate [MX] ≠ 0 at 35 °C is discussed in this paper. The observed data (k obs vs. [MX]) have been discussed quantitatively based on pseudophase micellar (PM) model. Such data treatment gives relative micellar binding constants of counterion X − and Br − (R X Br ) with FN. The effects of [MX] on the k obs have been coherence in terms of empirical equation and rheological data. The large catalytic effect of FN on the rate of piperidinolysis of PS − and rheological evidence of micellar structure correlate to the relative counterion binding constant, R X Br .
