“…DESs have many applications in various fields such as electrochemistry, medicine and pharmacology, biotechnology and bioengineering, and extraction/preconcentration processes. [7][8][9][10] Tiecco et al 11 reported novel chiral DESs composed of camphor sulfonic acid and ((S)-and (R)-N,N,Ntrimethyl-(1-phenylethyl))ammonium methane sulfonate. They examined the structural properties of chiral DESs and investigated their capability in the reaction media.…”
