Protic Ionic Liquids as Eco-Friendly Surfactants for Oil Spill Remediation: Synthesis, Characterization, and Performance Evaluation.

ABSTRACT: This study presents an innovative approach by synthesizing and evaluating protic ionic liquids (PILs) as sustainable surfactants for oil spill remediation, as an alternative to the highly toxic chemical dispersants conventionally used, as well as to the surface-active ionic liquids reported in the literature, which are typically based on imidazolium cations and halogenated anions. Four PILsbutyrolactam butyrate (BTB), 2-methyl-hydroxyethylammonium propanoate (2-HEAP), 2-methyl-hydroxyethylammonium acetate (2-HEAA), and choline laurate [CHL]-[LAU]were synthesized and analyzed for physicochemical and surfactant properties. Characterization included Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy, while density, viscosity, surface tension, and emulsificat
