The influence of the concentration of cationic (dodecylpyridinium bromide) and nonionic (Triton X-100) surfactants on the interaction energy between hydrophobic silica particles in aqueous solutions was investigated. It is shown that the effect of synergism in mixed surfactant solutions manifests in a reduction of the surfactant concentration required to reach a given interaction energy in comparison to the concentration required to reach the same interaction energy in solutions of individual surfactants. The parameters of interaction between surfactant mols. in their mixtures were calculated based the Rosen model. Chain-chain interactions between nonionic and cationic surfactants are assumed to be the main reason for the observed synergism. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Computed Properties of C17H30BrN).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridine has a conjugated system of six 锜?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H鐪塩kel criteria for aromatic systems. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C閳ユ弻 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Computed Properties of C17H30BrN
