| titleOfInvention | A kind of preparation method of 5-(2-hydroxyethyl) amino o-cresol |
| abstract | The present invention relates to a kind of preparation method of 5-(2-hydroxyethyl) amino o-cresol, it is characterized in that comprising the following steps: (1) condensation reaction: in certain solvent, 5-amino-2-methylphenol and Ethylene oxide carries out condensation reaction under catalyst action; (2) distilling: reaction solution underpressure distillation reclaims solvent, obtains 5-(2-hydroxyethyl) amino o-cresol crude product; (3) purification: 5-( The crude product of 2-hydroxyethyl) amino-o-cresol is processed through organic solvent recrystallization to obtain the refined product of 5-(2-hydroxyethyl) amino-o-cresol. The present invention reduces environmental pollution and cost while improving product quality, has simple operation, makes product production clean and environment-friendly, and makes the product more suitable for mass production. |
