Abstract: Disclosed in the present invention is an isoxazoline uracil compound crystallization method, comprising the following steps: preparing an isoxazoline uracil compound, washing an organic layer with water, and performing filtering; evaporating part of an organic solvent A and adding a solvent B; after heating, performing thorough mixing, cooling, and crystallization to obtain a slurry, performing solid-liquid separation, and performing drying to obtain a powdery solid. The present invention optimizes the amount of organic solvent A removed so that the mass ratio of the isoxazoline uracil compound to the organic solvent A in the remaining solution is 5:1-1:5, reducing the content of the solvent in an oily product, increasing the saturation of a target product in the solution, and facilitating further crystallization and purification. Further, the crystal form of the isoxazoline-containing uracil compound can be transformed, so that the isoxazoline-containing uracil compound transforms from an oily substance into a bundle-shaped crystal form or a crystal block, and changes from an oily state to a powdery state, improving transport and material storage during production of the isoxazoline- containing uracil compound and the product usability thereof, and expanding the application range of the product.
