| titleOfInvention | Method for obtaining lactic acid with a high degree of purity from fermentative liquor |
| abstract | The present invention describes a process for obtaining lactic acid with a high degree of purity from a fermentative liquor (1) containing sodium lactate, with a view to the production of polylactic acid. The process comprises the unitary operations of centrifugation (101), centrifugal decantation (102), microfiltration (103), ultrafiltration (104), primary filtration in an activated charcoal bed (105), conventional electrodialysis (201), ion exchange columns in a chelating resin bed (202), bipolar electrodialysis (203), ion exchange columns (204), primary evaporation under vacuum (302), secondary filtration in an activated charcoal bed (304), liquid-liquid extraction from the aqueous phase to the organic phase (305), back extraction from the organic phase to the aqueous phase (306), and secondary, atmospheric evaporation (402). |
