Abstract
The electrical conductivity of four surfactants, sodium caprylate, sod ium laurate sodium palmitate and sodium stearate in molten acetamide h as been determined at 90 degrees C. Conductivity measurements show tha t micelles are formed in acetamide solution. Critical micelle concentr ation (CMC) has been determined for each of the surfactants. It is sug gested that the simplest formula of the ionic micelle is (S-)(n)(CH3CO NH2)(x). At higher concentration the micelle may be of the forms (NaS) (m)(S-)(n)(CH3CONH2)(x) where NaS denotes sodium stearate.
