On the basis of neutron diffraction exptl. data, the activation energies of displacement of water mols. in the presence of nonionic and cationic micelle-forming surfactants have been estimated With increase in the concentration of nonionic surfactant (Triton X-100) even to the critical micelle-forming concentration, a decrease of the activation energy of displacements of water mols. is noticeable, but a decrease of the energy becomes not so significant with a subsequent increase of the concentration With increase of the concentration of cationic surfactant (dodecyl- and hexadecylpyridinium bromides) within the investigated concentrations, the activation energy of water mol. displacement increases. A procedure for estimating the activation energy in the presence of a homologous series of nonionic (oxyethylated alkylphenols) and cationic (alkylpyridinium bromides) micelle-forming surfactants is proposed. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4SDS of cas: 104-73-4).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.SDS of cas: 104-73-4
