Study of the polarity and hydrogen-bond ability of dodecyltrimethylammonium bromide micelles by the Kamlet-Taft solvatochromic comparison method

Article Abstract:

A study was conducted to analyze the dipolarity/polarizability, hydrogen-bond donor activity, and hydrogen-bond acceptor basicity of dodecyltrimethylammonium bromide micelles. The Kamlet-Taft solvatochromic comparison technique was utilized to examine the micelles. Experimental results indicated a very good agreement between solvatochromic and extra-thermodynamic studies. Findings also showed differences that affect the performance of micelles in their functions as catalysts, separation enhancers and emulsifiers.

Different theoretical approaches for the study of the mixed tetraethylene glycol mono-n-dodecyl ether/hexadecyltrimethyammonium bromide micelles

Article Abstract:

The mixed micelles tetraethylene glycol mono-n-dodecyl ether/hexadecyltrimethylammonium bromide were investigated. The surface tension results were studied on the basis of a treatment that takes into account the relation between the activity coefficients according to the Gibbs-Duhem equation. The results were compared with Rubingh's treatment, which considers the activity coefficients provided by the regular solution theory.

The chemical meaning of the standard free energy of transfer: Use of van der Waals' equation of state to unravel the interplay between free volume, volume entropy, and the role of standard states

Article Abstract:

A chemical interpretation of the standard free energy of transfer of a dilute solute from a nonideal phase to an immiscible nonideal phase is presented, based on the van der Waals model of a binary mixture.
