摘要： 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).

摘要： 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.
摘要翻译：一种通过气 - 液 - 固相体系中有机溶剂萃取制备适用于制备水溶性固体草甘膦制剂的草甘膦的方法，该方法包括将草甘膦和水加入到具有稳定剂的反应器中，引入氨以携带反应完成后，形成草甘膦铵水溶液; 加入水溶性有机溶剂如甲醇和/或乙醇和/或甲缩醛，以降低草铵膦在体系中的溶解度，从而结晶出草甘膦铵; 并抽吸过滤或进一步烘干，得到固体草甘膦。可以回收有机溶剂并通过精馏或蒸馏再利用，其余残余物可以返回到反应程序中或用于制备草甘膦铵的水性制剂。
