Milestone - Uses and synthesis methods
Toxicity
acute oral LD50>5000mg/kg in rats, acute percutaneous LD50>2000mg/kg in rabbits, and acute inhalation of LC50 in rats was 5.3mg/L. No irritation to rabbit eyes and skin. Ames test negative, no mutagenicity. The LC50 was 48mg/L (96h) for the big sunfish, 33mg/L (96h) for the rainbow trout and 38mg/L (48h) for the Daphnia.
production method
2, 4-dichlorophenol is made by etherification, nitration, and reduction to obtain the corresponding intermediate, and then diazotization and reduction to obtain the corresponding substituted phenylhydrazine; cyanoprene carbamate reacts with acetic anhydride to obtain the corresponding intermediate. The two intermediate products react and then heat the ring to prepare zolidinone.
