Potassium decanoate

In a study of pressure effects on sodium and potassium decanoate micelles, the frequency of the CH2 stretching band was found to increase with pressure, with a discontinuous drop at the critical coagelization pressure (75). These results indicate that external pressure applied to micelles induces hydrocarbon tail disordering, even at pressures as high as 20 kbar, followed by a large increase in tail ordering upon coagel formation. 

Clearly, the infrared spectra of the sodium and potassium decanoate micellar solutions are considerably different, as are their pressure dependencies. Since the only difference between these two micellar systems is the size, and thus the charge density of the counterions, the different infrared spectra must be taken as evidence that in the alkali decanoate micelles the sodium or potassium counter cations interact differently with the carboxylate groups of the surfactant molecules. 

Photocycloaddition of 3-fz-butylcyclopentanone in the presence of 1-octene in a potassium decanoate micelle yields the the head-to-head photoadduct as the major product, consistent with the notion that a micellar interface helps to orient the reactant molecules (Fig. 14). When the orientation of the reactive olefin is further controlled by adding a hydrophilic group,...

By using potassium decanoate as an example of a highly charged micelle of well-defined volume, the phase nature and extension for competing phases co-existing with micelles at the maximum admissible concentration (MAC) can be explicitly predicted. The polarity of the solute is modified through the value of the standard chemical potential, For a non-polar...

Kolthoff and Strides [137] showed an almost linear increase in the solubilizing capacity for dimethylaminobenzene, (DMAB) within the series, potassium dodecanoate to octadecanoate. Introduction of a double bond (potassium oleate), however, produced a decrease in solubilizing power as compared to a saturated compound of similar length. A branched chain compound (di-amylsulphosuccinate) solubilized less DMAB than did potassium tetradecanoate, but more than potassium decanoate (same number of carbon atoms in the longer chain), whereas dodecylamine hydrochloride showed a greater solubilizing power than potassium dodecanoate.
