      abstract     = {2,3-butanediol (2,3-BDO) is a versatile platform chemical
                      that can be produced via fermentation in aqueous solution.
                      The energy intensive recovery of the high boiling 2,3-BDO
                      from water via distillation hinders the economic viability
                      of biotechnological produced 2,3-BDO. Hence,
                      extraction-distillation processes using novel solvents from
                      the class of terpenoids, namely menthol, thymol, and
                      carvacrol, are proposed. To this end, binary and ternary
                      liquid-liquid equilibrium (LLE) data for H2O, 2,3-BDO, and
                      each terpenoid, as well as boiling point data for 2,3-BDO
                      and the respective terpenoid, are measured. The
                      thermodynamic phase equilibria are correlated with the
                      non-random two liquid (NRTL) model and consecutive process
                      design of the extraction-distillation processes is conducted
                      using Aspen Plus. Conventional solvents (isobutanol,
                      1-butanol, and oleylalcohol), thymol, and carvacrol are
                      assessed in terms of specific exergy demand for the
                      production of 2,3-BDO. The lowest specific exergy demands
                      were found for oleyl alcohol (5.38 kJ g−1) and thymol
                      (5.14 kJ g−1), carvacrol (5.49 kJ g−1). Hence,
                      terpenoids are a competitive class of solvents and should be
                      included in solvent screening approaches.},
