In this work we study influence of the length of the alkyl chain and temperature on critical micellar concentration (CMC) for cis and trans diastereoisomers of the N-alkyl-N-{[2-(benzyloxy)cyclohexylmethyl]}-N,N-dimethylammonium bromides in aqueous solutions using conductometric and spectrophotometric techniques. From the measured dependences, the degree of the counterion binding (β) and thermodynamic parameters of micellization (∆Gm0, ∆Hm0, ∆Sm0) were calculated and compared with the literature data on similar compounds. The results show that lengthening of the alkyl chain by one methylene group causes approximately a two-fold reduction in CMC. The β values decrease with temperature and with increasing length of the alkyl chain. While only a small decrease in the ∆Gm0 values (ca 1 kJ mol-1) due to increasing temperature was found, the decrease in ∆Hm0 is much more pronounced.

A semi-empirical kinetic technique has been used to obtain the ratios of pure CTABr (cationic nanoparticle) and mixed CTABr–C16E20 (cationic–nonionic nanoparticle) micellar binding constants of counterions X and Br, KX/KBr (=KBrX or RBrX) for X = salicylate ion.
