Abstract

Surface and thermodynamic properties of the oxyethylenated anionic surfactants C10H210C2H4S03Na, C12H2, 0C2H4S03Na, C,, HZ5OC2H4SO, Na, and C12HzS (OC2H4) 2S0, Na were investigated at 10, 25, and 40 OC in aqueous solution and in NaCl solution of 0.1 and 0.5 M total ionic strength. At all ionic strengths and temperatures studied, compounds with an oxyethylene group (EO) in the molecule are more surface-active than ...
