| titleOfInvention | A kind of bromination new process of 2,4- dinitroaniline |
| abstract | The invention discloses one kind 2, the bromination new process of 4- dinitroaniline, using bromides such as hydrogen peroxide and sodium bromides as bromating agent, by the way that 1- methyl -3- (4- sulfonic group) butyl imidazole hexafluorophosphate ionic liquid catalyst is added in the reaction, and carry out gradient increased temperature can be effectively facilitated reaction carry out can improve reaction selectivity, catalysis reaction rate, it is effectively facilitated reaction to carry out, promotes the yield of bromo- 2, the 4- dinitroaniline of 6-.Method provided by the invention is at low cost, easy to operate, and safety and environmental protection is easy to industrial applications. |
