    • 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.
    • 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。

    • The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The amino methyl phosphonic acid used in the methods of the invention has the formula R.sup.1 R.sup.2 NCH.sub.2 P(O)(OH).sub.2. In this formula, R.sup.1 and R.sup.2 are independently a C.sub.6 -C.sub.20 alkyl group or a CH.sub.2 P(O)(OH).sub.2 group. However, R.sup.1 and R.sup.2 are not both a CH.sub.2 P(O)(OH).sub.2 group. Alternatively, R.sup.1 and R.sup.2, together with the N, may also form a 5-8 membered heterocyclic ring having the formula: ##STR1## In the heterocyclic ring, X is O, NH, or CH.sub.2. The salt of an amino methyl phosphonic acid can be an acid salt or a quaternized amino methyl phosphonic acid salt. The invention also relates to a composition containing amino methyl phosphonic acids or salts thereof and useable in the above methods. The compositions comprise at least one amino methyl phosphonic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
    • 本发明涉及一种抑制细菌粘附在潜水表面上的方法。 该方法用有效量的至少一种氨基甲基膦酸或其盐接触潜水表面以抑制细菌粘附到潜水表面。 本发明还涉及一种用于控制水系统的生物污垢的方法。 该方法添加有效量的至少一种氨基甲基膦酸或其盐以抑制细菌粘附到水性体系内的浸没表面。 该方法有效地控制生物污染,而不会基本上杀死污染的生物体。 用于本发明方法的氨基甲基膦酸具有式R 1 R 2 NCH 2 P(O)(OH)2。 在该式中,R 1和R 2独立地为C 6 -C 20烷基或CH 2 P(O)(OH)2基团。 然而,R1和R2不是CH2P(O)(OH)2基团。 或者,R 1和R 2与N一起也可以形成具有下式的5-8元杂环:在杂环中,X是O,NH或CH 2。 氨基甲基膦酸的盐可以是酸性盐或季铵化的氨基甲基膦酸盐。 本发明还涉及含有氨基甲基膦酸或其盐的组合物并且可以在上述方法中使用。 组合物包含至少一种氨基甲基膦酸或其盐,其量可有效地抑制细菌粘附到潜水或浸没的表面。
