SYNTHESIS OF 2, 4-DICHLORO-4'-NITRO-DIPHENYLE—THER FROM Na_2CO_3, K_2CO_3 MEDIUM |
| |
| Abstract: | A new synthetic method of 2, 4-diclhoro-4'-nitro-diphenyle—ther has been ProPosed. This method is superior than the traditional method in the following respects. First, cheap Na_2CO_3 is used to replace part of the expensive K_2CO_3. Second, the salt is produced by refluxing the reactant in aqueous solution instead of adding solid K_2CO_3 to the reaction mixture. The quality of the product is improved and the cost is much lowered by this new method. |
