Tralomethrin Use and Manufacturing

Methods of Manufacturing

Preparation Method 1: In carbon tetrachloride solvent, dibromethrin acid is added with bromine, and reacted at 20℃ for 1h to obtain tetrabromide, which is then converted to tetrabromide chloride with sulfoxide chloride in DMF and petroleum ether , And then synthesis of tetramethrin with α-cyano-phenoxybenzyl alcohol. Preparation method Dipermethrin chloride can obtain higher yield through various ways, tetramethrin chloride can be prepared by exchange reaction and addition reaction of permethrin chloride with bromine, and then with α-cyano m-phenoxybenzene The synthesis of tetramethrin by the action of methanol. Preparation method Tri-tetramethrin and deltamethrin can be prepared by adding bromine in the presence of carbon tetrachloride.

Uses

Insecticide.
