One-pot synthesis of fuel precursor from acetoin fermentation broth using ionic liquid-based salting-out extraction system.

ABSTRACT:

Background

The development of biofuels, especially liquid hydrocarbon fuels, has been widely concerned due to the depletion of fossil resources. In order to obtain fuel precursors, the reaction of C-C bond formation is usually carried out with biomass derived ketones/aldehydes as reactants. Acetoin and 2,3-butanediol are two platform chemicals, which are co-existed in fermentation broth and traditionally separated by distillation, and then acetoin could be use as C4 building block to prepare hydrocarbon fuels. In order to mitigate the process complexity, direct aldol condensation reaction of acetoin in fermentation broth was studied in this work.

Results

A one-pot process of product separation and acetoin derivative synthesis was proposed based on salting-out extraction (SOE
