example 2

[0021] 10% triadimefon microemulsion preparation. Take by weighing 10.6 kilograms of 95% triadimefon former medicine, add 10 kilograms of xylenes, stir, heat and make it dissolve completely, add 7 kilograms of polyoxyethylene octylphenol ethers, 4 kilograms of nonylphenol polyoxyethylene ethers and 2.5 kg of sodium dodecylbenzene sulfonate, mix evenly, add 4 kg of ethylene glycol under stirring, mix evenly, add deionized water under high-speed stirring to make up to 100 kg; mix evenly, heat to 75°C, wait for stirring The system changes from W / O type to O / W type, and after cooling to room temperature after being a homogeneous liquid, a 10% triadimefon microemulsion is obtained.

example 3

[0023] 15% triazolone microemulsion preparation. Take by weighing 15.8 kg of 95% triadimefon technical substance, add 12 kg of ethanol, stir, heat to make it dissolve completely, add 6 kg of polyoxyethylene octylphenol ether, 5 kg of nonylphenol polyoxyethylene ether and 3.5 kg of Sodium dodecylbenzene sulfonate, mix evenly, add 4 kg of propylene glycol under stirring, mix evenly, add deionized water under high-speed stirring to make up to 100 kg; The W / O type is changed to the O / W type, and it is a homogeneous liquid and then cooled to room temperature to obtain 15% triadimefon microemulsion.

example 4

[0025] 20% triadimefon microemulsion preparation. Take by weighing 21.1 kilograms of 95% triadimefon technical substance, add 15 kilograms of methanol, stir, heat and make it dissolve completely, add 5 kilograms of polyoxyethylene octylphenol ethers, 6 kilograms of nonylphenol polyoxyethylene ethers and 2.5 kilograms of nonylphenol polyoxyethylene ethers under stirring Kilogram sodium dodecylbenzene sulfonate, mix well, add 4kg propylene glycol under stirring, after mixing well, add deionized water under high-speed stirring to make up to 100kg; mix well, heat to 75°C, wait for the stirring system to change from From W / O type to O / W type, after cooling to room temperature after being homogeneous liquid, 20% triadimefon microemulsion is obtained.

Abstract

The invention discloses a triazolone microemulsion and a preparation method thereof. The triazolone microemulsion comprises 5-20 percent of triazolone, 5-15 percent of solvent, 10-25 percent of emulsifier, 4-10 percent of antifreeze and balance of de-ionized water, and the sum of the raw materials is 100 percent. The preparation method comprises the following steps: the triazolone is firstly added into the solvent under the condition of heating, is stirred after being heated to dissolve and is added with the antifreeze and the emulsifier during the stirring, after the materials are evenly mixed, the stirring speed is accelerated and the de-ionized water is slowly added, the stirring is kept continuously, the materials are heated to 70-80 DEG C, and the sterilization microemulsion containing the triazolone can be prepared when the material system is stirred to be converted into O / W type from the W / O type and is cooled to be at the room temperature after being of homogeneous liquid. The invention is suitable for preventing and treating diseases of banded sclerotial blight of wheat, powdery mildew, and the like, has simple production method, safe storage and transportation and little influence on environment and is safe to human beings and livestock.

Description

technical field [0001] The invention relates to a pesticide fungicide, in particular to a triadimefon microemulsion and a preparation method thereof. Background technique [0002] As people pay attention to the living environment, it is required to reduce the environmental pollution caused by the use of pesticide products. In order to meet this social requirement, in the development of pesticide products, while focusing on the development of new varieties of pesticides with low toxicity and high efficiency, higher requirements are put forward for pesticide preparations, and the development of pesticide preparations is required to be solidified and water-based. [0003] Triadimefon, chemical name: 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H,1,2,4-triazol-1-yl)-2- Butanone. [0004] Structural formula: [0005] [0006] Experimental formula: C 14 h 16 N 3 o 2 Cl. Relative molecular mass: 293.8 (according to the international relative atomic mass in 1997). Physical and c...
