| titleOfInvention | PROCESSES FOR THE PRODUCTION OF LACTIC ACID AND FOR THE PREPARATION OF LACTIID AND / OR POLYLATIC ACID |
| abstract | process for lactic acid production. The present invention relates to a process for the preparation of lactic acid comprising the steps of: a) provided from an aqueous medium comprising magnesium lactate; b) adding to the aqueous medium comprising magnesium lactate a monovalent base to form an aqueous medium comprising a water soluble monovalent lactate salt and a solid magnesium base; c) separating the magnesium base from the aqueous medium comprising the water soluble monovalent lactate salt; d) adjusting the concentration of the monovalent lactate salt in the aqueous medium to between 10 and 30% by weight; e) submitting the aqueous medium comprising the monovalent lactate salt for water dissociation electrodialysis to produce a first solution comprising monovalent base and a second solution comprising lactic acid and monovalent lactate salt, the electrodialysis being performed at a partial conversion of 40 ° C. 98 mol%; f) separating the second solution comprising lactic acid and monovalent lactate salt into lactic acid and a solution comprising monovalent lactate salt by vapor-liquid separation; g) recycling the solution of step f) comprising the monovalent lactate salt to step d). |
