| titleOfInvention | Method for separating and recovering alkanediol monoalkyl ether, recycling method of photoresist composition treating waste liquid, and recycling method of photoresist composition treating liquid |
| abstract | The present invention provides a process for separating and recovering an alkanediol monoalkyl ether from a solvent mixture containing an alkylene glycol monoalkyl ether and its corresponding carboxylic acid ester and containing other solvents in high purity and high yield. By adding a basic compound to an alkylene glycol monoalkyl ether carboxylate containing an alkanediol monoalkyl ether (first solvent) and an alkylene glycol monoalkyl ether (first solvent) a solvent mixture of a solvent (third solvent) different from an alkanediol monoalkyl ether (first solvent) and an alkylene glycol monoalkyl ether carboxylate (second solvent), and an alkane After the saponification of the diol monoalkyl ether carboxylate (second solvent) is converted into an alkylene glycol monoalkyl ether (first solvent), the alkylene glycol monoalkyl ether (first solvent) is recovered by distillation. |
