| titleOfInvention | A kind of preparation method of N-[2-(2-hydroxyethoxy)-4-nitrophenyl]ethanolamine |
| abstract | The invention relates to a preparation method of N-[2-(2-hydroxyethoxy)-4-nitrophenyl]ethanolamine, which uses 2-amino-5-nitrophenol as raw material, and 2-amino- 5-nitrophenol is mixed with a base and a solvent, then added with a hydroxyethylating reagent, and reacted at a certain pressure and temperature to generate 2-(3-nitro-6-aminophenoxy)ethanol; 2-(3-nitro Base-6-aminophenoxy)ethanol reacts with chloroethyl chloroformate under the action of catalyst, and obtains N-[2-(2-hydroxyethoxy)-4-nitrophenyl] through condensation and hydrolysis ethanolamine. The invention has the advantages of high yield, high purity, good quality, mild production process, less generation of three wastes and the like; the invention is not only economical and environment-friendly, but also suitable for industrial production. |
