Removal and concentration of lower molecular weight organic acids from dilute solutions |
摘要 |
A process for obtaining lower carboxylic acids from aqueous lower carboxylic acid salts, such as obtained from a fermenter. The process involves converting the lower carboxylic acid salt to the corresponding acid with carbon dioxide, extracting the thus formed acid with a solvent and using the thus formed bicarbonate salt to buffer the fermenter.
