production method | the preparation method is 2-(2,4, 6-trichlorophenoxy) ethyl chloride and an appropriate excess of N-propylamine are put into the amination kettle, stirred and heated, reacted to a certain temperature, reacted for 8~10h, kept for 1~2H, and discharged under reduced pressure after the reaction, the resulting amine salt was destroyed with alkali, and N-propylamine was recovered, washed with water and extracted with toluene. The oil layer was distilled under reduced pressure to obtain a finished product. 2-(2,4, 6-trichlorophenoxy) ethyl bromide can also be used as raw material to mix with N-propylamine, heating and refluxing for 8H, removing n-propylamine after reaction, acidifying with hydrochloric acid, filtration gave a white solid as a finished product. |
