Abstract

Thermodynamics of micellar systems Part III : Apparent and partial heat capacities of sodium alkanoates

To obtain the heat capacities of the aqueous solutions of the sodium carboxylates, we carry out microcalorimetric heat capacities measurements. The aim of this work is to calculate the quantities of the apparent and partial molar heat capacities, and also to define the critical micellar concentrations. The variations of the partial molar heat capacities by increment -CH2 allows us to give prove for products supposed to form true micelles and products do not form micelles. To discuss the solute-solvent and solutesolute interactions we used the standard apparent molar heat capacities.
