The application provides a high-purity thermostable crystal form of a substituted 3-isoxazolidinone compound, a preparation method therefor and an application thereof. The High-purity thermostable crystal form is prepared by a particular method of the present technology and is determined by single-crystal X-ray diffraction as an orthorhombic crystal, featuring a space group of P212121 and lattice parameters of a=9.2301(2) Å, b=11.0751(3) Å, c=12.7554(3) A, α=90°, β=90°, and γ=90°. The orthorhombic crystal can be conveniently applied in preparation of agrochemical formulations, such as a suspension concentrate and a water dispersible granule, and the new formulations prepared have a better herbicidal activity and crop safety.
该应用程序提供了一种替代3-
异噁唑烷酮化合物的高纯度热稳定晶型,以及其制备方法和应用。该高纯度热稳定晶型是通过本技术的特定方法制备的,并通过单晶X射线衍射确定为正交晶体,具有P212121空间群和晶格参数a=9.2301(2) Å,b=11.0751(3) Å,c=12.7554(3) Å,α=90°,β=90°和γ=90°。该正交晶体可以方便地用于制备农药配方,如悬浮浓缩液和
水分散颗粒,制备的新配方具有更好的除草活性和作物安全性。
