68085-85-8 - Preparation Method
Open Data Verified Data
using methyl dimethyl pentenoate as raw material, the reaction was carried out with trichlorotrifluoroethane and peroxybenzoic acid in the presence of catalyst, further treated by saponification and the like to obtain 1,2-= chloro -3,3,3-fluoropropenyl -2 ',2'-= methylcyclopropylcarboxylic acid. On the other hand, in the presence of liquid alkali and methanol, M-phenoxybenzaldehyde is reacted with formaldehyde to obtain m-phenoxybenzyl alcohol, and then reacted with sodium cyanide solution under acidic conditions to obtain a-cyano-m-phenoxybenzyl alcohol. Finally, with thionyl chloride as chlorinating agent, the cyclopropanecarboxylic acid to form cyclic propionyl chloride, and then in the presence of pyridine, with a cyano a phenoxy benzyl alcohol made of cyhalothrin.

| action characteristics | cyhalothrin is also called cyhalothrin, cyhalothrin. It has the characteristics of efficacy, inhibition of insect nerve axon site conduction, the insect has the role of avoidance, knock-down and poison, broad insecticidal spectrum, high activity, rapid efficacy, after spraying, it is resistant to rain erosion, but it is easy to produce resistance to long-term use. It has a certain effect on the pests and mites of the puncture type mouth, and the mechanism of action is the same as that of fenvalerate and cyhalothrin. The difference is that it has a good inhibitory effect on mites, in the initial use of mites, can inhibit the number of mites to rise, when the mites have occurred in large numbers, it can not control its number, therefore, it can only be used for the treatment of insects and mites, and cannot be used for special acaricides. |
| pharmacodynamic use | lambda-cyhalothrin is a highly efficient, broad-spectrum, rapid-acting pyrethroid insecticide, the main effect was Contact killing and gastric toxicity, without internal absorption. The Lepidoptera, Coleoptera and Hemiptera and other pests and other pests, as well as spider mites, rust mites, mites, tarsal mites have a good effect, in insects, mites can be concurrent treatment, can control the cotton pink bollworm and cotton bollworm, cabbage, cabbage and rice tube aphid, tea geometrid, tea worms, tea spider mites, leaf spider mites, citrus leaf moth, orange aphid and citrus spider mites, rust mites, such as peach and pear, can also be used to control a variety of surface and public health pests. Such as prevention and control of cotton bollworm, cotton bollworm, in the second and third generation egg peak, with 2.5% emulsifiable concentrate 1000~2000 times liquid spray, and treatment of Red Spider, bridge insects, cotton mists, the vegetable aphid was sprayed at the concentration of 6~10mg/L and 6.25~12.5mg/L respectively, and the control of citrus leaf moth was sprayed at the concentration of 4.2~6.2mg/L. |
| Use | lambda-cyhalothrin is the pair of isomers with the highest insecticidal activity among the 16 stereoisomers of lambda-cyhalothrin. The product is mainly to kill and stomach poison, and has a certain repellent effect, with a broad spectrum of insecticidal, high efficacy, safety, long duration, resistance to rain wash, easy biodegradation, and after degradation does not produce toxic residues and other characteristics. It has a good killing effect on a variety of lepidopteran larvae, and can also effectively control some underground pests, and has a repellent effect on some adults. This product is a new type of pyrethroid insecticide, which has the effect of killing and stomach poison, no internal absorption, wide insecticidal spectrum, fast insecticidal effect and long lasting effect. This product can be widely used in the control of cotton, fruit, soybean, vegetables and other crops of Lepidoptera, Coleoptera and Homoptera pests. |
