Hydrophobic natural alcohols based deep eutectic solvents: Effective solvents for the extraction of quinine

Yunchang Fan et al.

Summary: The hydrophobic natural alcohols based deep eutectic solvents (NADESs) synthesized in this work showed high extraction ability for quinine, with NADESs of lower viscosity and stronger hydrogen bond accepting ability exhibiting stronger extraction ability. Quinine acted as a hydrogen bond acceptor in the hydrogen bonding with NADESs, and the extraction efficiency of NADESs for quinine was higher than other solvents such as ionic liquids, trichloromethane, and ethyl acetate. The NADES phase could be reused for extraction, and quinine could be recovered from NADES phase via back extraction with 1.0% acetic acid aqueous solution, showing potential as promising solvents for extraction of bioactive compounds.

Summary: This study investigates the impact of water on intermolecular interactions in deep eutectic solvents betaine/urea and choline/urea. The addition of water enhances intermolecular interactions in betaine/urea, hinting at the formation of aggregates, while in choline/urea, water has an asymmetric impact leading to weaker interactions in choline-rich mixtures and stronger interactions in urea-rich mixtures. This research provides insights into how water affects the interactions in these systems.
