| titleOfInvention | How to recover acetic acid solvent from waste sludge |
| abstract | The present invention relates to a method for recovering acetic acid solvent from sludge that is disposed of in the process of preparing terephthalic acid.n n n An object of the present invention is to facilitate the waste treatment by converting the acetic acid solvent in the sludge discarded during the production of terephthalic acid into methyl acetate and recovering the sludge to be flowable even at low temperatures.n n n According to the present invention, the sludge, methanol and esterification catalyst containing acetic acid solvent are introduced into a batch reactor and stirred, and the acetic acid contained in the sludge is converted into methyl acetate by esterification with methanol in the batch reactor. Provided is a method for recovering acetic acid solvent from sludge that is disposed in the process of preparing terephthalic acid, which comprises the steps of recovering the methyl acetate. |
