Use | O-methyl benzoyl chloride is a fungicide to kill Rust Amine, phenoxy Ester, the intermediate of trifloxystrobin and the herbicide bensulfuron-methyl. It is used in organic synthesis of medicines, pesticides, photosensitive materials, dyes, etc. In the pesticide industry for the preparation of O-amides and benzenes fungicides, mihuanglong herbicide. used in pharmaceuticals, pesticides, photosensitive materials and dye intermediates |
production method | O-Toluic acid as raw material production. The preparation method is to add the O-Toluic acid and the catalyst to the reaction kettle, heat it with steam to melt it, keep the temperature at 125 ℃, pass phosgene to react for 18h, sample and analyze whether the reaction is complete, the phosgene supply was stopped and the nitrogen supply was changed, and the heat preservation was continued for 0.5h. After cooling, the crude reaction product was obtained. O-methyl benzoyl chloride can also be obtained by using thionyl chloride, phosphorus oxychloride and the like as an acid chlorinating agent. |
