Purification method of terephthalaldehyde |
| abstract |
The present invention relates to a method of producing terephthalaldehyde of high purity by recrystallization of terephthalaldehyde crystals containing impurities using antisolvent, and specifically, the present invention relates to a low purity terephthalaldehyde obtained through a conventional manufacturing process. After dissolving in dimethyl sulfoxide, recrystallized with water using an anti-solvent to produce a terephthalaldehyde, using only water as an anti-solvent is not only environmentally friendly, but also easy to prepare a high purity terephthalaldehyde in a short time It is economical as it can be done. |
