| titleOfInvention | A process for the recovery of lactic acid esters and amides from aqueous solutions of lactic acid and/or salts thereof |
| abstract | The invention provides a process for the recovery of purified lactic acid values from an aqueous feed solution containing lactic acid. lactic acid salt, or mixtures thereof, comprising: bringing the feed solutio n into contact with a substantially immiscible anion exchanger to form a substantially water-immiscible phase comprising an anion exchanger - lactic acid adduct; effecting a condensation reaction in the substantially water-immiscible phase between a carboxylic moiety of the lact ic acid adduct and a moiety selected from a hydroxyl moiety and a primary or secondary amine moiety to respectively form a lactic acid ester or amine product: and separating the formed lactic acid product from the anion exchanger. |
