Small-angle X-ray scattering of the gadolinium triacetate–undecane–water system

详细

By small-angle X-ray scattering a gadolinium triacetate–undecane–water system is studied at hydrotrope concentrations of 0.05-0.5 М on the line of saturation with undecane at 298 K. In the ternary system mixed hydrotrope/undecane lamellar micelles form with lateral dimensions of hydrophilic and hydrophobic plates of 0.4 nm. It is shown that the Gibbs energy of the hydrophobic interaction and the micelle shape are determined by a joint (cooperative) effect of the hydrotrope and hydrocarbon on water.
