| titleOfInvention | PROCESS FOR PURIFYING GLYCOLIC ACID BY DISTILLATION |
| abstract | The subject of the invention is a method for purifying glycolic acid comprising the following steps: preparing a solution of free glycolic acid, concentrating said glycolic acid solution to a solids content of more than 60% by dry weight, of preferably between 60 and 80% by dry weight, distil the solution thus concentrated using a distillation technology allowing a very short residence time, less than 5 min, preferably between 0 and 2 minutes, and recover the glycolic acid thus distilled. |
