Abstract
A process for bio-1,3-butanediol purification from a fermentation broth includes the steps of: (a) subjecting the fermentation broth to separation, (b) subjecting the product obtained in step (a) to treatment with ion-exchange resins, (c) subjecting the product obtained in step (b) to a first evaporation, (d) subjecting the product obtained in step (c) to a second evaporation; and (e) subjecting the product obtained in step (d) to a third evaporation, obtaining purified bio-1,3-butanediol. The purified bio-1,3-butanediol can be used to produce bio-1,3-butadiene. Bio-1,3-butadiene can be used as a monomer or as an intermediate to produce elastomers and (co)polymers.
