5. Synthesis method:
There are many methods for synthesizing 4,4′-dihydroxydiphenyl ether, the most common ones include:
- Phenol and acetyl chloride reaction method: Phenol and acetyl chloride react to generate an intermediate, and then undergo alcoholysis to obtain the target product.
- 4,4′-diaminodiphenyl ether diazotization hydrolysis method: 4,4′-diaminodiphenyl ether is hydrolyzed after diazotization to obtain 4,4′-dihydroxydiphenyl ether, but this method has problems such as easy explosion of diazonium salt and low yield.
- Fixed bed reactor method: After preheating 4,4′-diaminodiphenyl ether, it is brought into a fixed bed reactor with water vapor and reacted under the action of a catalyst. This method can reduce the reaction pressure, improve safety, and simplify the process.
