Mixing of menthol-based hydrophobic deep eutectic solvents as a novel method to tune their properties

Due to the limited number and water-immiscibility of hydrophobic deep eutectic solvents (hDESs), new methods of expanding the repertoire and tuning the properties of these solvents are required. Here, menthol was combined with organic acids or alcohols to produce nine hDESs, all of which were freely miscible with each other. Three of the hDESs, vis. ML, MB, and MT (containing menthol combined with levulinic acid, 1,3-butanediol, and...
