SIMPLE APPARATUS FOR SOLUBILIZATION OF VOLATILE SUBSTANCES INTO SURFACTANT SOLUTION

A very simple glass vessel was devised as an apparatus to determine th e solubilization of volatile or gaseous substances. The apparatus work ed well for production of constant chemical potential of the solubiliz ate. With use of the apparatus, the first stepwise association constan t of benzene and micelle of n-dodecylammonium perfluoroacetate was fou nd to remain constant irrespective of the amount of benzene. This resu lt indicates constancy of monomeric solubilizate concentration in aque ous surfactant solutions of various concentrations.
