| titleOfInvention | The method for preparing the fluoro- 2,4- dinitrobenzene of 1,5- bis- |
| abstract | The invention discloses a kind of methods for preparing the fluoro- 2,4- dinitrobenzene of 1,5- bis-.This method is using m-difluorobenzene as starting material, and under the mixed system of the concentrated sulfuric acid and fuming nitric aicd, fluoro- 2, the 4- dinitrobenzene of 1,5- bis- is made through nitration reaction.Synthesis process of the invention is very easy, and reaction condition is mild, and raw material are cheap and easily-available, and by-product is less in preparation process, and yield is higher, and does not need recrystallization operation and the product of higher degree can be obtained, and can carry out industrialized production. |
