Choosing a suitable surfactant can control its solubilization property easily by controlling the operating conditions. As a new green solvent, it has potential application in the fields of chemical reaction, material preparation and extraction and separation. This paper describes the basic concepts of the supercritical CO2 microemulsion / reverse micellar system, and summarizes and summarizes the theoretical research results on the thermodynamic properties, surfactant selection, phase behavior, hydraulics size calculation, and agglomeration particle interactions. On this basis, some applications in this field are analyzed and discussed.
