Use | 2, 4-dichloro-5-isopropoxyaniline is an important dye, pharmaceutical and pesticide intermediate, in particular, the synthesis of 1,2, 4, 5-tetrasubstituted benzene nitrogen-containing heterocyclic herbicides such as oxadiazinone, 2-[2, 4-dichloro-5-(1-methylethoxy) phenyl]-4-(2-fluoroethyl)-1,2, 4-triazine-3, 5(2H, 4H)-Dione and the like. 2, 4-dichloro-5-isopropoxyaniline is an intermediate of the herbicide oxadiazinone. |
production method | the preparation method is to add 2, 4-dichloro-5-isopropoxy nitrobenzene, the hydrogenation catalyst, promoter and methanol, replace the air in the kettle with hydrogen for 3 times, maintain the hydrogen pressure in the kettle at 2.0 MPa, start stirring, and maintain the hydrogen pressure at the appropriate temperature at 2.0 MPa, after adding hydrogen for several hours, the reaction can no longer absorb hydrogen, sampling and testing, the reaction is finished, stirring is stopped, standing for a period of time, pressure is released, the material is pressed out and filtered to remove the catalyst, the product was then obtained by desolvation under reduced pressure. |
