Molecular connectivity indices for modeling the critical micelle concentration of cationic (chloride) Gemini surfactants
The molecular connectivity indices were used to derive the simple model relating the critical micelle concentration of cationic (chloride) gemini surfactants to their structure. One index was selected as the best to describe the effect of the structure of investigated compounds on critical micelle concentration consistent with the experimental results. This index encodes the information about m...
متن کاملModelling of the Critical Micelle Concentration of Cationic Gemini Surfactants Using Molecular Connectivity Indices
Modelling of the critical micelle concentrations (cmc) using the molecular connectivity indices was performed for a set of 21 cationic gemini surfactants with medium-length spacers. The obtained model contains only the second-order Kier and Hall molecular connectivity index. It is suggested that the index 2χ includes some information about flexibility. The obtained model was used to predict log...
متن کاملQSPR Study for Predicting Critical Micelle Concentrations of Gemini Surfactants
CMC (critical micelle concentration) is lowest concentration when micelle was created in aqueous solution of surfactant. In this study, we collected CMC data to develop the QSPR model of gemini surfactants from literatures. Gemini surfactants are composed of two monomeric surfactant molecules linked by a spacer chain. Gemini surfactants can self-assemble at concentrations almost a hundred-fold ...

The behavior of pr imary, secondary, tert iary and quaternary dodecylammonium chloride and bromide in benzene and toluene was investigated by surface tension measurements , the dye-solubilizafion and iodine-complex formation method and vapor pressure osmometry a t 37 ° and 50°C. The smooth cont inui ty in the measured properties of these solutions as a function of concentration has been interpr...
متن کاملQSPR Study of Critical Micelle Concentration of Anionic Surfactants Using Computational Molecular Descriptors
A data set of 181 diverse anionic surfactants has been investigated to relate the logarithm of critical micelle concentration (cmc) to the molecular structure using Comprehensive Descriptors for Structural and Statistical Analysis (CODESSA Pro) software. A fragment approach provided superior quantitative structure-property relationship (QSPR) models in terms of statistical characteristics and p...
