QSPR 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...
متن کاملPrediction of Critical Micelle Concentration Using a Quantitative Structure-Property Relationship Approach. 1. Nonionic Surfactants
Aquantitative structure-property relationship studywasperformedon the criticalmicelle concentration (cmc) of nonionic surfactants using the CODESSA program. A known correlation between the logarithm of the cmc and counts of linear alkane carbon atoms and ethoxy groups in linear alkyl ethoxylates was improved (R2 ) 0.996) by adding cross terms of these molecular descriptors. A general three-para...
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 کاملPrediction of the Critical Micelle Concentration of Nonionic Surfactants by Dissipative Particle Dynamics Simulations.
Micellization of surfactant solutions is a ubiquitous phenomenon in natural systems and technological processes, and its theoretical description represents one of the cornerstone problems in the physical chemistry of colloidal systems. However, successful attempts of quantitative modeling confirmed by experimental data remains limited. We show, for the first time, that the dissipative particle ...
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 ...
