Propargite is a broad-spectrum, high-efficiency, and low-toxicity acaricide. The original drug is a yellow-brown viscous liquid, which has contact and stomach poisoning effects, and has no penetration and systemic effects. It has good effect on juvenile nymphs and adult mites, but poor ovicidal effect. The application effect is good above 20°C, and the application effect is poor at low temperature. When used in high concentration and high temperature, it may cause phytotoxicity to some crops, but it is safe at the usual dose.

The production method of propargite

Mix tert-butanol and sodium hydroxide, heat to 150°C, add 1,2-epoxycyclohexane dropwise within 1 hour, and keep the reaction at 150-160°C. After dropping, stir for half an hour, add xylene, cool to 100°C, neutralize with concentrated sulfuric acid, evaporate part of the xylene, take out the water generated by neutralization, and obtain the xylene solution of 2-cyclohexanol. Heat to 60°C, add thionyl chloride within half an hour, stir at 5-10°C for 2.5h, and place outside for 15h. Then evaporate the volatile substances under reduced pressure and heat to obtain 2-cyclohexyl chlorosulfonate. Finally, it was added to the mixture of propargyl alcohol, pyridine and xylene, stirred at 5-15°C for half an hour, the reactant was washed with water, the aqueous layer was extracted with ether, and post-treatment was performed to obtain dexafenate.
