Abstract

The chain length dependence of precipitation/redissolution behavior of a Na alkylsulfonate/CaCl₂ system is investigated. Results obtained here clearly show that the precipitate redissolution occurs in the presence of micelles. Solubility product, CMC, and even the solubilization constant decrease with an increase in chain length. The dependence of these parameters on chain length has been used to estimate such thermodynamic parameters as free energy contribution per -CH₂- group toward precipitation and micellization. Based on these results subprocesses involved in the precipitation/redissolution phenomena are discussed.
