Abstract

The invention provides an environmentally friendly and efficient propiconazole emulsifiable concentrate, which comprises the following components by mass: 10 to 70% of propiconazole, 1 to 10% of emulsifiers and the balance of dibasic esters. In the environmentally friendly and efficient propiconazole emulsifiable concentrate and a preparation method thereof, the dibasic esters are mixed with the propiconazole, which can dissolve propiconazole technical materials well and the obtained emulsifiable concentrate has good stability and dispersion. Compared with traditional emulsifiable concentratepreparations, the environmentally friendly and efficient propiconazole emulsifiable concentrate has no organic solvent pollution and a high flash point, and is safer in production, storage and use. The dibasic ester has a wide range of sources and low cost, which reduces the cost of the emulsifiable concentrate.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to an environment-friendly and high-efficiency propiconazole emulsifiable concentrate and a preparation method thereof. Background technique [0002] EC is one of the basic dosage forms, which has the advantages of low processing cost, simple preparation, and good drug efficacy. However, EC contains a large amount of aromatic solvents, such as toluene, benzene, xylene, and acetone. These solvents are not only harmful to the environment, ecology and Food safety causes cumulative hazards, but also has strong volatility and flammability, and there are many unsafe factors. Therefore, the fundamental way to solve the problem of emulsifiable concentrate must be to find safe and environmentally friendly substitutes for solvents such as aromatic hydrocarbons, so as to complete the green upgrade of emulsifiable concentrate. [0003] Dibasic acid ester (DuPont call...
