Assessment of extraction options for a next-generation biofuel: Recovery of bio-isobutanol from aqueous solutions.

ABSTRACT: Isobutanol is a widely used platform compound and a raw material for synthesizing many high value-added compounds. It also has excellent fuel properties and is an ideal gasoline additive or substitute with a very broad development space. Isobutanol production by biological fermentation has the advantages of a comprehensive source of raw materials, low cost, environmental protection, and sustainability. However, it also has disadvantages such as many impurities, low isobutanol concentration, and difficulty separating the water + isobutanol azeotrope. Thus, it is necessary to explore an appropriate downstream separation process for the water + isobutanol azeotrope. K₂CO₃ with a strong salting-out effect was used as the salting-out agent, and the salting-out of isobutano
