Abstract: The invention relates to a two-way approach to isolate, recover and upgrade 2,3-Butanediol (2,3-BDO) from fermentation broth. A complete separation and recovery process for 2,3-BDO using acetalization and trans-acetalization sequence. Acetalization with butyraldehyde using heterogeneous catalysts, either Amberlyst-15® or Nafion NR50®, efficiently isolates 2,3-BDO as phase-separated protected dioxolane. The approach provides significant process advantages with easy product recovery and high recyclability of the catalyst. Trans-acetalization of dioxolane with methanol (methanolysis) followed by distillation of acetal, yielded very high purity 2,3-BDO with about 90% isolated yield. Alternatively, dioxolane is used in a process direct to methyl ethyl ketone (MEK) as a BDO synthon allowing for recovery of the aldehyde.
