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

Abstract

The effect of apparent catalysis at different concentration of flexible nanoparticles (FN), (FN = CTABr|MX|H2O) of piperidine with phenyl salicylate ion when substituted sodium phenolate [MX] ≠ 0 at 35 °C is discussed in this paper. The observed data (kobs 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 kobs 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 .
