METHOD FOR CLEANING TRIFLURALINE |
| abstract |
There is described the purification of trifluralin for reducing the nitrosamine content and for stabilising it against the formation of new nitrosamines. To this end, crude trifluralin is treated in countercurrent with saturated or superheated steam at temperatures from 70 to 120@C. |
