| Use | pyrethroid insecticide with contact killing and gastric toxicity. The medicament is permeated through the insect epidermis or ingested after the medicament treatment leaves enter the body. By inhibiting the ability of ion channel closure, tetrabromide interferes with the ion channel that regulates the flow of sodium ions, causing too much sodium ions to enter the cell, thereby generating nerve Impulse amplitude to the nerve cell, finally, nerve cells completely disappear excitement, paralysis, collapse and death. Tetrabroma can be used to control Coleoptera, Homoptera, Orthoptera pests, especially lepidopteran pests on cereals, cotton, corn, fruit trees, tobacco, vegetables, rice. Dosage: 0.075~1.95g/100. |
| production method | preparation method 1. In carbon tetrachloride solvent, dibromosulinic acid and bromine are added and reacted at 20 ℃ for 1H, tetrabromo-pyrethroid acid is obtained and then converted to tetrabromo-pyrethyl chloride with thionyl chloride in DMF and petroleum ether, and then tetrabromo-pyrethroid is synthesized with α-cyano-m-phenoxybenzyl alcohol. Preparation Method: The higher yield can be obtained by a variety of ways, and the tetrabradine chloride can be obtained by the exchange reaction and the addition reaction of the two, tetrabromothrin was synthesized by the reaction with α-cyano-m-phenoxybenzyl alcohol. The preparation method of tritetrabromothrin can be obtained by adding bromine to deltamethrin in the presence of carbon tetrachloride. |
