Abstract:
The present invention concerns a method for purifying an aqueous lactic acid solution, obtained from a fermentation medium or from any other source previously cleared of solid substances and/or of biomass that may be present and ionic substances, characterised in that it comprises the two following steps: a. Concentration of the lactic acid solution until a concentration of between 85 and 95% is reached, preferably of between 90 and 95%, i.e. between 15 and 5% free water or preferably between 10 and 5% free water; b. Distillation in a multi-stage column comprising three areas and allowing the separation, in a single step, of the lactic acid, volatile compounds and the heaviest impurities.

Claim (Index 7):
The purification process as claimed in  claim 4 , wherein the heat input of the distillation column is provided by a reboiler that makes it possible to minimize any thermal and chemical degradation.
