Efficient flucypermethrin is a synthetic pyrethroid insecticide with contact and gastric toxic effects. It has a wide insecticidal spectrum, rapid knockdown, and a long shelf life. Plants have good resistance to it.
Chemical property
High efficiency cypermethrin pure product is a white solid, while industrial product is a light yellow solid. m. P.49.2 ℃, vapor pressure 200 × 10-9Pa (2.67 × 10-7Pa (20 ℃). Refractive index n24D1.534, b. p.187~Chemicalbook190 ℃/26.7Pa. Easy to dissolve in various organic solvents such as acetone, methanol, ethyl acetate, toluene, etc., with a solubility of>500g/L; Insoluble in water. Stable storage at room temperature for more than six months; Half life in water under sunlight for 20 days; The half-life in soil is 22-82 days.
Efficient cypermethrin is a representative variety of pyrethroid insecticides, and it is the pair of isomers with the highest insecticidal activity among the 16 stereoisomers. This product mainly has contact killing and gastric toxic effects, and has a certain repellent effect. It has a wide insecticidal spectrum, high efficacy, safety, long shelf life, resistance to rainwater erosion, easy biodegradation, and does not produce toxic residues after degradation.
Application
Efficient cypermethrin is mainly used for the control of pests in the order Lepidoptera, Coleoptera, Hemiptera, Thymidoptera, Hymenoptera, Orthoptera, Diptera, as well as cockroaches in cotton, fruit trees, vegetables, tea trees, and dry grains.
Domestic registration status
Efficient cypermethrin is one of the insecticides with a relatively high number of registered products in the Chemicalbook, and its raw material (mother liquor) product registration is also relatively high. From the first enterprise registration in 1997 to the end of 2014, more than 80 domestic and foreign enterprises registered 729 products of raw materials and formulations. In recent years, there have been many registered compound products, mainly nicotine based mixtures.
Preparation method
1. Synthesis of trifluorochlorohydrin chloride: trifluorochlorohydrin reacts with sulfoxide chloride, desolves, and distills to obtain trifluorochlorohydrin chloride.
2. Synthesis of chlorofluorocyanide crude oil: Chlorofluorocyanide crude oil is synthesized by using trifluorochloropyrethroid chloride, meta phenoxybenzaldehyde, and sodium cyanide as catalysts.
3. Efficient synthesis of chlorfluazuron: Chlorofluazuron crude oil undergoes differential isomerization under the action of organic amines, producing efficient chlorfluazuron.
