Patent number: 9221853Abstract: This invention provides the herbicidal active ingredient, a dimethylamine salt crystal of N-phosphonomethyl glycine (glyphosate), its preparation process and a solid formulation containing the crystalline dimethylamine salt of glyphosate as well as its application. Said preparation process comprises adding glyphosate and a suitable amount of solvent into a conventional reactor and introducing a dimethylamine gas for reaction, wherein the reaction temperature is controlled between 5 and 90° C. After the completion of the reaction, the temperature is reduced slowly to a certain value, a crystalline dimethylamine salt of glyphosate is precipitated (or precipitated after a crystal seed is added).Type: GrantFiled: October 25, 2010Date of Patent: December 29, 2015Assignee: ZHEJIANG WYNCA CHEMICAL INDUSTRY GROUP CO., LTD.Inventors: Wei Wang, Shuguang Zhou, Long Qin, Bufan Ren, Zhigang Qian, Tao Liu, Huiling She, Yaxian Zhang

Patent number: 7435847Abstract: A method of preparing ammonium glyphosate suitable for preparation of water-soluble solid ammonium glyphosate formulation by an extraction with organic solvent in a gas-liquid-solid phase system, which comprises adding glyphosate and water into a reactor with a stirer, introducing ammonia to carry out the reaction, an aqueous solution of ammonium glyphosate is formed after the reaction is completed; adding a water-soluble organic solvent such as methanol and/or ethanol and/or methylal to decrease the solubility of the ammonium glyphosate in the system, thereby crystallizing out ammonium glyphosate; and filtering in suction or further oven-drying to obtain the solid ammonium glyphosate. The organic solvent may be recovered and reused by rectifying or distilling, the remainder residue may be returned to the reaction procedure or used in the preparation of the aqueous formulation of ammonium glyphosate.Type: GrantFiled: September 4, 2003Date of Patent: October 14, 2008Assignee: Zhejiang Xin'Inventors: Wei Wang, Bufan Ren, Shuguang Zhou, Min Bao, Hongchao Zheng, Baiqing Zhang, Jiang Li
