NIST chemical information Information provided by: webbook.nist.gov (external link)
EPA chemical information Information provided by: ofmpub.epa.gov (external link)
toxicity acute oral LD50 in rats is 224 mg/kg (male) and 187 mg/kg (female), acute inhalation LC50 is 0.61~1.53mg/L (1h), and acute percutaneous LD50 in rabbits and rats is> 2000 mg/kg. The 90-day feeding test in rats had no effect at a dose of 20mg/kg. The 2-year feeding test for large and mice had no effect on the dose of 20mg/kg per day. The mutagenic test was negative and had no adverse effect on reproduction. No teratogenic effect, no carcinogenic effect (mice) was found in the feed with a content of 2500mg/kg. No delayed neurotoxicity. Quail LC50 is 1229mg/kg (feed). Carp LC50 was 0.55mg/L (48h). The LD50 of bees is 0.678mg/bee.
use carbamate insecticide, acaricide and nematicide with high systemic and broad spectrum. It is a low-toxic variety of carbofuran, which is used to control aphids, mites, golden needle worms, sugar beets, potato beetles, tea leafhoppers, pear heartworms, apple leaf curls and other pests of citrus, fruit trees, cotton, and rice crops. The application concentration is 5mg/L, and the dosage is 6.8~15g active ingredient/100 m2.
It is used for the control of more than ten kinds of pests such as rust ticks, aphids, thrips, leafhoppers, etc. on fruit trees, cotton, vegetables, grains and other economic crops
It is a low-toxic insecticide with systemic and broad-spectrum
This product is a derivative of carbofuran, which has the same insecticidal activity as carbofuran, but its toxicity is much lower than carbofuran, and it is a gastric toxic insecticide, it is metabolized into carbofuran in the organism and then exerts its pharmacodynamic effect to kill insects. It has good control effect on potato green peach aphid, black light beetle, high-staining blind horned fly, cutworm and other pests. In addition, there are also better control of cotton red spider, cereal elephant, miscellaneous cereal thief, pink armyworm, etc.
Production method Dibutylamine reacts with sulfur dichloride to obtain dibutylamino sulfur chloride, and then reacts with carbofuran.
preparation method dibutylamine and petroleum ether (60~90 ℃) are added into dibutylamine and petroleum ether (60~90 ℃), stirred and cooled to 0 ℃, then slowly added disulfur dichloride dropwise, maintained at 0~10 ℃, and reacted for 2h after addition. the ratio of dibutylamine, disulfur dichloride and sulfuryl chloride is 1:0.6:0.55(mol), and the yield is 88%. Synthesis of carbosulfan di-n-butylamino sulfur chloride reacts with carbofuran in a ratio of 1:1. Add appropriate amount of lye during the reaction process, and the reaction temperature is 10~20 ℃. The reaction time was 2h. After the reaction, add water and stir for 10min, filter, filter pool for unreacted carbofuran, can be used back. The filtrate is stratified, the oil layer is desolated under reduced pressure, and the yield is 90%. Preparation method The synthesis method of the two intermediate hydroxyl compounds is shown in Carbofuran. There are also reports in the literature that starting from cyclohexanone and isobutyraldehyde, they are synthesized in five steps through acetyl aldehyde condensation, chlorination, aromatic cyclization, hydrolysis, and closed-loop reaction. It is characterized by the synthesis of non-aromatic compounds, which is a highly selective synthetic route.
