Abstract
Deep Eutectic Solvents (DESs) have emerged as a distinct class of solvents with unique properties and advantages over conventional Ionic Liquids (ILs) and organic solvents. This study specifically focuses on evaluating the potential of DESs as aggregation inhibitors for asphaltenes. Utilizing the Conductor-like Screening Model for Real Solvent (COSMO-RS) method, we investigated a series of DESs based on choline chloride and menthol. The COSMO-RS approach enabled the accurate prediction of key thermodynamic properties, including density, σ profiles (charge distribution), and σ potentials (electrostatic potential) of the DESs. Our findings identified eight DESs as particularly effective in dispersing asphaltenes, providing a promising foundation for further experimental validation and potential application in the petroleum industry.
