Toward surfactant-free and water-free microemulsions.

摘要: It was recently demonstrated that a nano-clustering present in the monophasic “pre-Ouzo” region of ternary liquid mixtures without surfactants. The goal this work is to check if also surfactant-free and water-free “green” microemulsions glycerol/ethanol/1-octanol deep eutectic solvent/tetrahydrofurfuryl alcohol/diethyl adipate. solvents used instead water were ethylene glycol–choline chloride (molar ratio 4–1) urea–choline 2–1). To our knowledge first time formulate microemulsions. studied using phase diagrams, dynamic light scattering, small-angle X-ray scattering. presence aggregate fluctuations they found be independent molecular critical fluctuations, except when approaching point where phenomenon superimposed signal. These structures have similarities classical but, contrast them, having sharp interface between non-miscible phases, much as it case for systems previously investigated like water/ethanol/oil, oil 1-octanol, fragrance molecules, or mosquito repellents.
