摘要：

A series of n-alkyltriethylammonium compounds with n-alkyl chains between 4 and 16 carbon atoms has been prepared and submitted to electrocapillary and differential capacitance measurements at a dropping mercury electrode in 1 N potassium chloride. The results indicate that these are more strongly adsorbed than the corresponding compounds with trimethylammonium headgroups. The ratios of the differential capacitances for the two types of compound, calculated from the thicknesses of the adsorbed layers, are in good agreement with the experimental values.
