Method of producing lactic acid and polylactic acid |
| abstract |
A method of producing lactic acid includes filtering a lactic acid-containing aqueous solution through a nanofiltration membrane to recover an aqueous lactic acid solution from the permeate side (Step A); distilling the aqueous lactic acid solution to recover lactic acid from the vapor side (Step B); and crystallizing the lactic acid obtain in Step B, and performing solid-liquid separation to recover a lactic acid crystal(s) (Step C). |
