| LogP | 5.7 |
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| toxicity | the original drug has an acute oral LD50 of 2200 mg/kg in rats and 920 mg/kg in mice. The acute percutaneous LD50 in rabbits was 3476mg/kg(>10000mg/kg). Acute inhalation of LC50 in rats was 2.5mg/L. It has a stimulating effect on rabbit eyes and skin. Rats subacute oral non-acting dose 40 mg/kg, chronic oral non-acting concentration 300 mg/kg. Under the experimental conditions, no carcinogenic, teratogenic and mutagenic effects were found in animals. Trout LC500.118 mg/L (96h), blue gill sunfish LC500.197 mg/L (96h), carp LC50 1.0mg/L (48h). Acute oral LD50 of bees is 18.13mg/bee. |
| use | broad spectrum, high efficiency, low toxicity acaricide, with contact killing and stomach toxicity, no penetration and absorption. It has good effect on juvenile mites and mites, and poor egg killing effect. The application effect is good above 20 ℃, and the effect is poor at low temperature. Used at high concentrations and high temperatures, it may cause phytotoxicity to certain crops and is safe at common doses. Used for mites control on cotton, fruit trees, tea trees and other crops. Used for the control of citrus spider mites, rust mites, apples and hawthorn spider, with 73% emulsifiable concentrate 2000~3000 times liquid spray; used for the control of cotton spider, tea orange gall mite, gall mite with 1500~2000 times liquid spray. Broad-spectrum acaricide, with stomach poison and contact killing effect. It has special effects on mites and mites, but it is harmless to natural enemies. It is suitable for mites control on cotton, fruit trees, tea trees and other crops. The LD50 of rats with acute oral toxicity was 2200mg/kg. The acaricide can effectively control leaf mites on apple trees, cotton, cucumbers, grapes, corn, soybeans, tomatoes and vegetables |
| production method | mix tert-butanol and sodium hydroxide, heat to 150 ℃, add 1,2-epoxy hexane dropwise within 1h, and keep it at 150-160 ℃ for reaction. After dropping, stir for half an hour, add xylene, cool to 100 ℃, neutralize with concentrated sulfuric acid, evaporate part of xylene, and bring out the water generated by neutralization to obtain 2-(p-tert-butyl phenoxy) xylene solution of cyclohexanol. Heat to 60 ℃, add thionyl chloride within half an hour, stir at 5-10 ℃ for 2.5h, and place outdoors for 15h. The volatile substances are evaporated by heating under reduced pressure to obtain 2-(p-tert-butyl phenoxy) cyclohexyl chlorosulfonate. Finally, it is added to the mixed solution of propargyl alcohol, pyridine and xylene, stirred at 5-15 ℃ for half an hour, the reactants are washed with water, the water layer is extracted with ether, and after post-treatment, the mites are obtained. preparation of 2-(p-tert-butyl phenoxy) cyclohexanol mixed with sodium hydroxide, heated to 150 ℃ (or special catalyst at 105-110 ℃), added 1, 2-epoxycyclohexane dropwise within 1h, kept at 150-160 ℃ for reaction, dripped, stirred for 30min, added xylene, cooled to 100 ℃, neutralized with concentrated sulfuric acid, steam out part of the xylene and bring out the neutralized water. Preparation of 2-(p-tert-butyl phenoxy) cyclohexyl chlorosulfonate The xylene solution of 2-(p-tert-butyl phenoxy) cyclohexanol prepared by the previous reaction is heated to 60 ℃, thionyl chloride is added within 0.5h, stirred at 5-10 ℃ for 2.5h, placed at room temperature for 15h, and then distilled under reduced pressure to remove volatile substances. Synthesis of propargyl mites The 2-(p-butyl phenoxy) cyclohexyl chlorosulfonate prepared by the previous reaction was added to the mixture of propargyl alcohol, pyridine and xylene, stirred at 5~15 ℃ for 30min, washed with water, extracted with ether in the water layer, and post-processed to obtain propargyl mites. See the literature [3] for the synthesis of high-content alkyne mites. |
