| Popis: | This paper describes the determination of counterion binding constant, R X Br , and CNP (CTABr/MX/H 2 O)-catalyzed rate constants, k cat , for the reaction between piperidine and phenyl salicylate ion, PS − (where X = 2- and 4-propyl as well as 3, and 4-isopropyl phenolate ions). A plausible reaction mechanism is discussed for CNP catalytic reaction. The calculated mean values of R X Br are 66.3 ± 3.7, 153 ± 8, 60.8 ± 5.5 and 66.6 ± 2.3 for X = 2,4-propyl, 3- and 4-isopropyl phenolate ions, respectively. Similarly the mean values of k cat are 0.51 ± 0.09, 1.22 ± 0.07, 0.47 ± 0.07 and 0.53 ± 0.07 M −1 s −1 , respectively. |
