A series of heterocyclic surfactants were prepared with pyridine and 1-bromoalkanes (bromooctane, bromodecane, bromododecane or bromotetradecane). The best reaction conditions for synthesis of the target products were optimized by orthogonal test program. The reaction temperature was 90鎺矯, the reaction time was 5 h, and the mole ratio of bromoalkane and pyridine was 1 : 1. The products were characterized by IR and ¹H NMR. The target products’ sterilization properties for colibacillus, staphylococcus aureus, bacillus subtilis were determined The results showed that the heterocylic surfactants had excellent sterilization properties for the above three kinds of bacteria.

Micellar counterion binding for alkylpyridinium iodides probed by N-sulfopropylacridinium fluorescence quenching was written by Asakawa, Tsuyoshi;Iriyama, Keisuke;Ohta, Akio;Miyagishi, Shigeyoshi. And the article was included in Journal of Oleo Science in 2004.Application In Synthesis of 1-Dodecylpyridin-1-ium bromide This article mentions the following:

Fluorescence quenching using N-sulfopropylacridinium (SPA) makes it possible to determine the degree of micellar counterion binding (灏? of alkylpyridinium iodide in aqueous solution But with quinoline derivatives as a halide-sensitive fluorescence probe, this was not possible. Fluorescence was quenched by iodide ions as indicated by linear Stern-Volmer plots, the slope of which was noted to decrease beyond cmc (critical micelle concentration) owing to micellar counterion binding with SPA excitation at 416 nm. The slope was found to significantly increase beyond cmc with SPA excitation at 357 nm. The abrupt quenching was due to absorption bands resulting from charge-transfer interactions of pyridinium and iodide ions. SPA fluorescence was quenched by iodide and bromide ions but virtually unaffected by nitrate or sulfate ions. Selective counterion binding of iodide ions is thus shown to be detectable. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Application In Synthesis of 1-Dodecylpyridin-1-ium bromide).

The effect of intermol. interactions on processes of micelle formation and adsorption in binary mixtures of non-ionic Triton X100 (TX100) with ionic sodium dodecyl sulfate and dodecylpyridinium bromide surfactants was studied. The ionic surfactants have identical hydrophobic alkyl chain and different hydrophilic groups. A feature of the used binary surfactant mixtures is that critical micelle concentrations and surface activity of the individual components are considerably different. A synergetic effect of decreasing of the surface tension was found in the surfactant mixtures It was shown that the mixed adsorption layers and the micellar phases are enriched with the nonionic surfactant. For both sodium dodecyl sulfate/TX100 and dodecylpyridinium bromide/TX100 systems, the synergetic effects were most pronounced at a high molar fraction of the nonionic surfactants in the mixture By using the Ruben-Rosen model, mol. interaction parameters in the mixed micelles βm, and in the adsorption layers βσ were evaluated. As was shown βm and βσ parameters to be notably higher for sodium dodecyl sulfate/TX100 mixture In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Product Details of 104-73-4).

The dynamics of cations in pyridinium-based ionic liquids by means of quasielastic- and inelastic neutron scattering was written by Burankova, Tatsiana;Reichert, Elena;Fossog, Verlaine;Hempelmann, Rolf;Embs, Jan Peter. And the article was included in Journal of Molecular Liquids in 2014.SDS of cas: 104-73-4 This article mentions the following:

Neutron scattering is an excellent tool to study the dynamics of hydrogen-rich materials. In the present work we subsumed our results on pyridinium-based ionic liquids We have performed inelastic, quasielastic and elastic neutron scattering experiments aiming to understand the different dynamical processes that occur at different temperatures in ionic liquids Using quasielastic scattering we obtained data that can be described as a superposition of localized dynamical processes and long range diffusion. The localized processes, which originated from the alkyl chain and the pyridinium ring of the cation, have been modelled in terms of the so-called Gaussian model. The influence of the length of the alkyl chain, attached to the cation, on the dynamical processes was discussed in detail. Furthermore we show neutron backscattering data, obtained on partially deuterated samples, that clearly demonstrate the melting of the alkyl chain and the activation of Me end-group rotations at low temperatures Finally, the power of deuterium labeling was evidenced for inelastic neutron scattering data. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4SDS of cas: 104-73-4).

The ternary system of dodecylpyridinium bromide (DDPB)/acetone/H₂O with appropriate composition can form a gel spontaneously and the gel is stable in hydrophobic ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF₆). Based on the gelation phenomenon we observed, the low mol. weight gelator (LMWG) was first tried to immobilize horseradish peroxidase (HRP) on glassy carbon electrode (GCE). The scanning electron microscope (SEM) images, the UV-Vis spectra and the bioactivity measurement indicate that the gel is suitable for the immobilization of HRP. The direct electrochem. of the HRP-gel modified GCE (HRP-gel/GCE) in [Bmim]PF₆ shows a pair of well-defined and quasi-reversible redox peaks with the heterogeneous electron transfer rate constant (k_s) being 14.4 s^-1, indicating that the direct electron transfer between HRP and GCE is fast. The HRP-gel/GCE is stable and reproducible. Also the electrode exhibits good electrocatalytic effect on the reduction of trichloroacetic acid (TCA), showing good promise in bioelectrocatalysis.

Degree of counterion binding of alkylpyridinium halide micelles: its relation to micelle shape and size was written by Fujio, Katsuhiko;Maruyama, Yasuhide;Uzu, Yuhei. And the article was included in Journal of Oleo Science in 2005.Electric Literature of C17H30BrN This article mentions the following:

From electromotive force measurements with surfactant and halide ion-selective electrodes, the authors obtained the degree of counterion binding (β) of dodecylpyridinium bromide (DPB) and iodide (DPI) and tetradecylpyridinium bromide (TPB) micelles in aqueous Na halide solutions with concentrations of 0-20 mM. Under a geometrical consideration the micelle shapes and the surface densities of head group (s^-1) of these micelles were deduced from aggregation numbers evaluated from their relations to the added salt concentration previously reported. The spherical micelles of TPB having the shape of an oblate ellipsoid had a constant β, 0.76, independently of s^-1. In the case of the spherical micelles of DPB, β is 0.79 for sphere-shaped micelles and 0.82 for ellipsoidal ones. For DPI the authors obtained β values of 0.84 and 0.99 for the spherical micelles with the shape of an oblate ellipsoid and the rodlike micelles, resp. From these dependences of β on micelle shape and s^-1, β of micelles studied increases in the order of sphere-shaped < oblately ellipsoidal < rodlike micelles but is independent of the micelle size unless the micelle shape changes.
