Effect of double bonds in the formation of sodium dodecanoate and sodium 10-undecenoate mixed micelles in water.
The micellization of an aqueous mixture of sodium dodecanoate (SDD) and sodium 10-undecenoate (SUD) was studied with the theory of mixed micellization. A strong nonideality was found, with a preferential composition of mixed micelles. This phenomenon was interpreted on the basis of the interaction between the vinyl group and water by hydrogen bonding. The importance of the aliphatic pi electrons and water was stated.
