摘要： Provided are a method of preparing a malononitrile oxime ether compound and an intermediate compound. The malononitrile oxime ether compound has a structure as shown in formula (VII), wherein W is selected from aryl or heteroaryl. The preparation method comprises steps: reacting a first raw material with a second raw material in the presence of a first solvent and a catalyst to obtain the intermediate compound, wherein the first raw material has a structure as shown in formula (IV), and the second raw material has a structure as shown in formula (V); and subjecting the intermediate compound as shown in formula (VI), and a dehydrant to a dehydrantion reaction in the presence of a second solvent to obtain the malononitrile oxime ether compound. In the preparation process for the intermediate, a cheaper cyanoacetamide is used as a raw material, the reaction conditions are mild. Moreover, the yield of the intermediate compound is high and the cost of the process is low. Furthermore, the required malononitrile oxime ether compound is obtained only through one-step dehydration reaction. Using the preparation method, is advantageous for improving the yield of malononitrile oxime ethers and reducing the cost of the process.

摘要： The present invention provides a polymorph of a benzamide compound and a preparation method and applications thereof. The shown benzamide compound is 3-Bromo-N-[2,4-dichloro-6-[(methylamino)carbonyl]phenyl]-1-(3,5-dichloro-2-pyridinyl)-1 H -pyrazole-5-carboxamide. The application of the polymorph of the compound in the preparation of the formulation exhibits excellent effect. The advantages of the polymorph A in aspects such as chemical stability, filterability, solubility, hygroscopicity, melting point, solid density and flowability can have a significant impact on the developments of the production method and a formulation and on the quality and efficacy of a plant treating agent.
