storage method
this product should be sealed and stored in a dry place away from light.
synthesis method
1-alkylcarbonyl-2,4,6-trichlorobenzene is prepared by fuckers acylation of 1,3,5-trichlorobenzene; the 1-alkylcarbonyl-2,4,6 -the oxidation reaction of trichlorobenzene produces 2,4,6-trichlorobenzoate; and the acidification reaction of the produced 2,4,6-trichlorobenzoate produces 2,4,6- trichlorobenzoic acid.
purpose
used in the synthesis of medicines, insecticides, and fungicides
