Use of the theory of Lifshitz-Slyosov-Wagner for the evaluation of the aqueous solubility of dodecane

The solubility of dodecane was determined using the theory of Lifshitz-Slyosov-Wagner for the Ostwald ripening phenomenon. For this purpose, a set of dodecane in water nanoemulsions stabilized with sodium dodecylsulfate was prepared. The average cubic radius of the dispersions was followed as a function of time for volume fractions between 0.001 and 0.00001. The correct solubility (5.5 x 10-9 m3/m3) was only reproduced by the most dilute system.
