Abstract
A series of ternary systems water/sodium dodecylsulfate (SDS)/ketone for different ketones ranging from propanone to 2-octanone are studied in some detail as well as the quaternary system water/SDS/2-pentanone/n-dodecane. Phase diagrams, elec. conductivities and one small angle neutron scattering spectrum of these systems are given and compared to corresponding results of systems contg. aldehydes instead of ketones. From this comparison it follows a remarkable analogy between the systems contg. a linear aliph. aldehyde with n-carbon atoms and those contg. 2-ketones with n+1 carbon atoms. It is concluded that the recently suggested co-surfactant behavior of aldehydes can also be discussed for ketones. As far as the elec. cond. is concerned this analogy is also shown for water/AOT/aldehyde and water/AOT/ketone systems.
