Abstract

The invention discloses a bupirimate microemulsion and a preparation method thereof, wherein the bupirimate microemulsion comprises 5-25 percent of bupirimate, 0.5-15 percent of solvent, 0.5-10 percent of cosolvent, 1-5 percent of penetrant, 8-20 percent of surfactant, and the balance of water. The bupirimate microemulsion has simple and easy production process, high production efficiency, good drug effect and improved drug utilization ratio, overcomes a plurality of defects of the prior drug forms, reduces the pressure to the environment from organic solvents, avoids the dust pollution, and improves the product safety in producing, packaging, transporting and using processes.

Description

technical field [0001] The invention relates to a pyrithrimol sulfonate microemulsion and a manufacturing method thereof, belonging to the technical field of pesticide preparation processing. Background technique [0002] Acrimolsulfonate, chemical name: 5-butyl-2-ethylamino-6-methylpyrimidin-4-yl dimethylaminosulfate, English common name Bupirimate, molecular formula: C 13 h 24 N 4 o 3 S, molecular weight: 316.42, CAS number: 41483-43-6, light brown waxy solid, melting point 51-52°C, vapor pressure 0.067mPa (20°C). Solubility at room temperature: water 23mg / L (pH value 5.2), soluble in most organic solvents, hydrolyzed in case of dilute acid, unstable when stored above 37°C for a long time. The drug is a pyrimidine systemic fungicide, and its mechanism of action is an adenosine deaminase inhibitor. It has protective and therapeutic effects, and can be quickly absorbed by plant roots, stems, and leaves, and transported to various parts of the plant. Therefore, it is res...
