| titleOfInvention | A kind of preparation method of the dibromobenzene compounds with alkoxyl group |
| abstract | The present invention relates to a kind of preparation method of the dibromobenzene compounds with alkoxyl group, organic solvent, alkoxy benzene compounds, bromine and nitrogen peroxide are joined in reactor, closed reactor, magnetic agitation more than 0.2 hour in air atmosphere, by chromatography over CC, obtain the dibromobenzene compounds with alkoxyl group.In preparation method of the present invention, reaction can effectively be carried out at normal temperatures, and reaction raw materials and catalyzer simple cheap, under the reaction conditions of the best, bromine raw material dosage is few, reduces production cost, and the productive rate of product is high, and the Hydrogen bromide the like waste of generation is few. |
