Abstract

The solution behavior of octyl-, decyl-, dodecyl-, tetradecyl-, hexadecyl-, and octadecylamine hydrochloride in 2-methoxyethanol at 25°C was determined by conductance techniques. Data were evaluated by the Fuoss-Shedlovsky, Fuoss-Onsager, and the Fernandez-Prini expanded form of the Pitts and Fuoss-Hsia equations. As expected, the limiting equivalent conductances of the electrolytes decrease as the crystallographic radii of the cations of these salts increase. Little difference is observed in the extent of association of the six long-chain quaternary ammonium salts in 2-methoxyethanol; these salts appear to behave as simple 1∶1 electrolytes within the concentration range of 1–28×10−4M. Included in the present study is a discussion of the previously investigated conductance behavior of these colloidal electrolytes in water.
