用途有機合成原料。
一般的な説明2-Benzoxazolinone is a phytoanticipin and its biotransformation by endophytic fungi isolated from Aphelandra tetragona was studied. 2-Benzoxazolinone is a natural chemical produced by rye (Secale cereale) and has strong phytotoxic properties.
製造方法2-benzoxazolinone synthesis method: add o-aminophenol, urea and solvent chlorobenzene into the reaction kettle, protect with nitrogen, the reaction temperature is 50~132 ℃, the reaction time is 6h, after the reaction is completed, it is cooled with ice brine, crystallized, Filter the finished product. It is also possible to use o-aminophenol to react with phosgene in the solvent chlorobenzene, quickly pass phosgene within 20 ~ 40 ° C, then heat up to 100 ~ 130 ° C, and then pass phosgene at a lower speed, after the reaction is completed, pass nitrogen to catch up. Phosgene, after work-up, can also obtain 2-benzoxazolinone.
