摘要： The invention discloses a core-shell structured anionic nano microemulsion system, and preparation and application thereof. The system comprises an anionic Gemini surfactant, an oil phase material, a solubilizer and water; wherein the microemulsion has a core-shell structure, with the outer shell being an anionic Gemini surfactant, and the inner core being an oil phase material. The anionic Gemini surfactant is N,N,N′,N′-dodecyl tetrasubstituted diphenyl ether sulfonate having the structural formula: The anionic nano-microemulsion system of the present invention is homogeneous and transparent, has a spherical core-shell structure, has a nanometer size (3 to 40 nm) as droplets, has a narrow particle size distribution, is not easy to agglomerate, has good stability, and has an ultra-low interfacial tension and a capability of reducing viscosity of crude oil.

摘要： The invention discloses a core-shell structured non-ionic nanoemulsion system and the preparation and use thereof. The system comprises a non-ionic gemini surfactant, an oil phase material, a solubilizer, and water; wherein the microemulsion has a core-shell structure, with the outer shell being the non-ionic Gemini surfactant, and the inner core being the oil phase material. The non-ionic Gemini surfactant is di(octylphenol polyoxyethylene ether)-substituted dicarboxylic acid diphenyl ether having the structural formula: The non-ionic nanoemulsion system of the present invention is homogeneous and transparent, and has a spherical core-shell structure with nanometer-sized (3-40 nm) droplets, narrow particle size distribution, low tendency to agglomerate, good stability, and both an ultra-low interfacial tension and the ability to reduce viscosity of crude oil.
