| titleOfInvention | Recovery method of high purity alkyl lactate and lactic acid |
| abstract | The present invention relates to a method for recovering high purity alkyl lactate and lactic acid from lactic acid fermentation broth, specifically, preparing a raw material solution containing lactic acid or ammonium lactate (step 1); Removing moisture of the raw material solution prepared in step 1 (step 2); Preparing a mixed solution by sequentially adding and stirring an alcohol and an acid solution to the raw material solution from which the water is removed in step 2 (step 3); Separating and removing the ammonium salt precipitate from the mixed solution of step 3 (step 4); Preparing an alkyl lactate through an esterification reaction from the mixed solution from which the ammonium salt precipitate is removed in step 4 (step 5); And distilling the mixture prepared in step 5 to separate alcohol and alkyl lactate (step 6), and to hydrolyzing the high purity alkyl lactate recovered by the recovery method. It provides a method for recovering high-purity lactic acid, characterized in that it is recovered by. The recovery method of the present invention does not require an expensive pretreatment device such as a conventional electrodialysis device or a membrane, and can produce alkyl lactate and lactic acid at low temperature, thereby recovering high purity lactic acid more economically than conventional methods. There is an effect that can be, and also has an effect that can be easily separated and reused ammonium sulfate generated as a by-product. |
