Abstract
The ability of a number of ionic liquids to extract 1,3-propanediol and 2,3-butanediol from aqueous solution was investigated. A range of hydrophobic ionic liquids were prepared and compared. The long chain phosphonium salts containing the trihexyltetradecyl phosphonium [P66614] cation exhibited promising extraction behavior. Among them, [P66614] [octanesulfonate (C8SO3)] combined high hydrophobicity, good stability, and relatively high extraction efficiency with the distribution coefficient DBDO = 0.390 and extraction selectivity SBDO = 4.83 (2,3-butanediol) and DPDO = 0.219 and SPDO = 2.65 (1,3-propanediol) at 25 °C. Additionally, this material exhibited good compatibility with the fermentation process, facilitating its use in bioprocesses.
