| titleOfInvention | Method for preparing bromopentafluorobenzene from pentafluorobenzoic acid in one step |
| abstract | The invention discloses a method for preparing bromopentafluorobenzene from pentafluorobenzoic acid in one step, belonging to the technical field of fine chemical engineering. Pentafluorobenzoic acid and a brominating reagent are used as raw materials, and are heated to react under the action of a catalyst, and then the pentafluorobromobenzene is obtained through distillation and rectification. The preparation method can complete decarboxylation and bromination in one step, has the advantages of easily-obtained raw materials, low cost, high yield, small environmental pollution and easy industrial production. |
