Oil-based cuttingsCleaningDryingn-Hexane,tert-butanol and water can form an effective surfactant-free microemulsion.The oil content of oil-based cuttings deoiled by surfactant-free microemulsions is lower than 1%.The surfactant-free microemulsion can be recovered and reused efficiently....
Surfactant-free microemulsions (SFME) comprising a cleavable hydrotrope/hydrophobic component were investigated regarding potential applications for green, microemulsion-mediated extraction processes. To this purpose, dynamic light scattering (DLS) experiments were performed for ternary systems consisting of water...

SurfactantA surfactant for water/supercritical carbon dioxide microemulsions that can achieve high water dispersion ability, water/supercritical carbon dioxide microemulsion forming ability under a moderate condition, and high water solubilization rate and that reduces burden on the environment and ecosystem. ...
Surfactant-free microemulsions (SFMEs) cleaning technology can effectively separate and recover petroleum pollutants from oil-based drilling cuttings (OBDCs). The identification of the molecular composition of OBDCs is helpful to accurately grasp the conversion mechanism of organic matter. Ther...
Surfactants (or amphiphiles) are generally believed to be a necessary component of microemulsions. However, research has found that in the absence of traditional surfactants, microemulsions can also form in a ternary system of two immiscible fluids and an "amphi-solvent". Such microemulsions are ...
microemulsionsstatic light scatteringOuzo effectCheers! The combination of static and dynamic light scattering is demonstrated to deliver an unambiguous proof that well-defined domains of two fluids of clearly different composition can exist in surfactant-free ternary mixtures (see picture for diagram), ...
This paper aims to report the conductivity measurement of ten different surfactant-free microemulsions (SFMEs)Design/methodology/approach The variations of electrical conductivity as a function of water volume fraction are examined at one constant alcohol (or DMF, ethyl lactate, 纬-valerolactone)/water...
However, as a major drawback the conventionally used SDS based microemulsions are not compatible with electrospray ionization mass spectrometry (ESI-MS). In this work, a surfactant-free microemulsion (SFME) consisting of water, ethanol, and 1-octanol is used for surfactant-free microemulsion ...
