Abstract
Apparent pseudo second-order rate constants, kX, for flexible nanoparticles, FNs, (CTABr/M2X/H2O)-catalyzed piperidinolysis of anionic phenyl salicylate, PSa−, at a constant [CTABr], 0.1 M piperidine (Pip) and temperature, were calculated from an empirical equation. CTABr = cetyltrimethylammonium bromide and X2− = 4-methoxysalicylate (4-MeOSa2−) and 3-,4-methylsalicylate (3-,4-MeSa2−) with Sa2− representing −O-C6H3CO −2 . The values of kX/k0 = μ measure the apparent rate enhancement due to FN catalysis for piperidinolysis of PSa− at a constant [CTABr] and temperature. The values of μ decrease with the increase in [CTABr] within the range of 5–15 mM.
