Abstract
A process for the manufacture of alkaline earth salts of acetic acid. Biomass is fermented under appropriate conditions to produce acetic acid, which is extracted from the fermentation broth with the aid of a basic liquid ion exchanger dissolved in an organic phase. The organic phase containing the product acetic acid is then reacted directly with a basic material such as limestone, and the resulting alkaline earth acetate product is recovered from the aqueous phase.
