Chemical properties
New distillation of single product is colorless transparent sticky liquid, in the air when light gradually become a dark purple, b.p. 167 ~ 169 ℃, industrial purity can reach 95% or make any concentration of toluene solution.
use
4 - (3, 5 - dichloro - 1,1,2,2 - four fluorine ethoxy) aniline was bell urea insecticides fluorine intermediates.
Production methods
Its preparation methods is in the presence of catalyst, 2, 6 - dichloro - 4 - aminophenol fluoride with tetrafluoroethylene, namely get 3, 5 - dichloro - 4 - (1,1,2,2 - four fluorine ethoxy) aniline.
Will be 2, 6 - dichloro - 4 - aminophenol and DMF, KOH solution in proportion, the bonus from the tower to drench, access from the tower of tetrafluoroethylene fluorination reaction, then through desolventizing recovery DMF, with toluene purified, quick needed products.
