Flucarbenzuron - Preparation Method
Open Data Verified Data
hydrogen fluoride, 4-nitrophenol and carbon tetrachloride were mixed and reacted with stirring to obtain 4-nitrophenyl trifluoromethyl ether, and 4-(-fluoromethoxy) aniline was obtained by reduction. 2 monochlorobenzamide and oxamide are reacted under reflux in 1,2-= ethyl chloride and the solvent is then distilled off under reduced pressure to give 2 monochlorobenzoyl isocyanate. 2-chlorobenzoyl isocyanate is then refluxed with 4-(-fluoromethoxy) aniline in benzene to give the aminourea.

Flucarbenzuron - Use
Open Data Verified Data
benzoylurea insecticides, inhibitors of chitin synthesis from turfgrass. The role of slow, no absorption, there is a certain Contact killing effect, but also with egg killing activity. Can be used for corn, cotton, soybean, fruit trees, forests, vegetables and other crops, the control of Coleoptera, Diptera, Lepidoptera, larvae of pests of the family, control of cotton bolls, Moth, Moth, houseflies, mosquito, cauliflower butterfly, West abietic color roll moth, potato leaf nail, can also be used to control termites. The dosage was 0. 561g/100. The formation of exoskeleton can be hindered by the larval molt, and the sensitivity of the larvae at different ages to the drug has no big difference, so it can be used in all the instar of the larvae.

rat, mouse oral LDso>5000mg/kg; Rat percutaneous LDso>5000mg/kg; Rat inhalation LC50>0.12mg/L air. The guinea pigs did not show any allergic effect. Rats with chronic feeding test had no effect dose of 20 mg/kg. Mutagenic effects have not been established in in vivo and in vitro studies in animals. Fish LD50>5000mg/kg, non-toxic to bees.

Rats with chronic feeding test no effect of the dose of 20 mg/kg feed. In vivo and in vitro experiments did not determine its mutagenic effect. Fish LC5050 ~ 100mg/L (96H), quail acute oral LD50>5000mg/kg, non-toxic to bees. |
| Use | benzoylurea insecticide, chitin synthesis inhibitor, it is an insecticide with a non-systemic gastric toxicity with limited contact killing effect. It is suitable for the prevention and control of chewing mouth insects, and is not effective for Pipette type insects (in addition to the genus wood lice and orange cloud rust mites). The formation of exoskeleton when the larvae molt is hindered by the effect of the drug, and the sensitivity of the larvae at different ages is not much different, so it can be used in all stages of the larvae. The agent also has egg-killing activity. Can be used for corn, fruit trees, forest, cotton, soybean, vegetables and other functions, control of Coleoptera, Lepidoptera, Diptera, wood lice family of armyworm, cotton bolus, diamondback moth, musca domestica, mosquitoes, cauliflower butterfly, West abietic color roll moth, potato leaf nail, can also be used to control termites. The dosage was 0.561g/100. A benzoylurea insecticide, which can inhibit a variety of forest pests |
| production method | the preparation of 2-chlorobenzoyl isocyanate see the preparation method of chlorobenzoyl urea. Preparation of p-trifluoromethoxyaniline hydrogen fluoride was introduced into a reactor containing carbon tetrachloride and p-nitrophenol. The reaction was carried out for 2H at 100 ℃ and then heated to 150 ℃, reduction with hydrogen gave p-trifluoromethoxyaniline. Synthesis of acetylisourea with benzene as solvent, 2-chlorobenzoyl isocyanate reacted with P-trifluoromethoxyaniline and refluxed for 1H to prepare acetylisourea. |
