| titleOfInvention | New preparation method of insect repellent albendazole |
| abstract | The invention discloses a new preparation method of an insect repellent albendazole and provides a brand-new synthesis route of albendazole. The new preparation method adopting m-dichlorobenzene as the starting material is used for obtaining high-purity albendazole through nitration, amination, condensation, reduction and cyclization reaction; the new preparation method is characterized in that an unstable intermediate condensation compound 2-nitryl-4-propyl sulfenyl aniline in the existing industrial route is changed into 2-nitryl-5-propyl sulfenyl aniline with stable quality. The reducing process is changed into a clean and efficient reducing process by virtue of sodium sulfide. The synthesis process is simple and efficient, less in pollution, high in quality and suitable for industrial production. |
