| titleOfInvention | Method for recovering and recycling L-tartaric acid |
| abstract | The invention provides a method for recovering and recycling L-tartaric acid. The method comprises the following steps of: performing acidification and precipitation specific to waste water containing tartaric acid diammonium generated in a process for splitting racemic 4-methylsulfonylphenyl serine ethyl ester to form and separate a tartaric acid hydrogen ammonium salt; and acidizing and desalting to obtain a methanol solution of the L-tartaric acid. The method can be directly applied to the splitting process of racemic 4-methylsulfonylphenyl serine ethyl ester, and the recovery and recycling of the L-tartaric acid are realized. The method provided by the invention has mild reaction conditions and simple process operation, and the production cost of the splitting process can be greatly lowered. |
