Uses | p-chloro-trichlorotoluene is the herbicide trifluralin, oxyfluoroflurane, trifluorocarboxane ether, fomesafen, and glycolfoxam Intermediate. Used as a pharmaceutical intermediate |
production method | its preparation method is to add p-chlorotoluene to the photachlorination reactor, turn on the frozen brine or cooling water of the condenser, raise the temperature and turn on the ultraviolet lamp, pass in chlorine gas to start the chlorination reaction, control a certain reaction temperature, stop passing chlorine gas when the reaction reaches the end point, remove chlorine gas and hydrogen chloride from the chloride material, and distill the finished product under reduced pressure. |
