A process for recovery of formic acid |
| abstract |
The invention relates to a process for the recovery of concentrated high purity formic acid having a concentration of at least 50%, most preferably at least 95%, from biomass wherein an aqueous liquid mixture containing levulinic acid and possibly furfural is subjected to a liquid-liquid extraction step, followed by the recovery of furfural, formic acid and levulinic acid. |
