| titleOfInvention | Method for purifying terephthalaldehyde |
| abstract | The present invention relates to a method for preparing high-purity terephthalaldehyde which comprises re-crystallizing terephthalaldehyde crystals containing impurities, using an anti-solvent. Specifically, the present invention relates to a method for preparing terephthalaldehyde which comprises dissolving low-purity terephthalaldehyde prepared by a conventional method in dimethylsulfoxide and then re-crystallizing the solution, using water as an anti-solvent. The present invention is not only environment-friendly because it uses water only as an anti-solvent, but also economical because it may simply prepare high-purity terephthalaldehyde in a short time. |
