Chlorempenthrin - Reference Information
| introduction | chlorene pyrethrin is a light yellow oil with light fragrance, boiling point: 128~130 ℃(40Pa), refractive index nD211.5047,nD211.5037. The vapor pressure is 0.413Pa at 25 ℃. Insoluble in water, soluble in various organic solvents. |
| use | chlorene pyrethrin is a new type of pyrethroid insecticide with high efficiency and low toxicity, which has good effects on mosquitoes, flies and cockroaches. It has the characteristics of high vapor pressure, good volatility, and strong killing power. It can knock down pests quickly, especially during spraying and fumigation. Novel pyrethroid insecticide, with stomach toxicity and contact killing activity, and has a certain fumigation effect. It has good stability and no residue. In addition to controlling sanitary pests, it can also be used to control storage pests. Spray method to control houseflies, the dose is 5.8~10mg/ m3; each tablet containing 250mg of medicine electric mosquito coil heating to 150 ℃, the killing rate of Culex pipiens pallens reached 80% ~ 100%. When the dose was 0.2mg, the killing rate of larvae of large black fur fur sac was 100%. It has a considerable control effect on houseflies, mosquitoes and cysticercosis, and can be used for household hygiene and storage pest removal |
| toxicity | acute oral LD50 in mice is 7900mg/kg. Under common dosage conditions, there is no irritation to human eyes, nose, skin and respiratory tract. The Ames test was negative. |
| Production method | 3-hydroxy-4-methyl-4, 5-alkenyl-1-heptyne is made from 2-methyl-2-pentenal and acetylene Sodium reaction preparation. 3-Hydroxy-4-methyl-4, 5-alkenyl-1-heptyne reacts with dichlorochrysanthemum chloride to produce chloromethrin. |
