    Abstract: A process for oxidizing a hydroxymethylphosphonic acid compound to produce a formylphosphonic acid compound is described. The oxidation reaction is carried out in the presence of an oxidant and a catalyst. For example, hydroxymethylphosphonic acid (HMPA) is oxidized by oxygen or hydrogen peroxide in the presence of a copper-containing catalyst to give formylphosphonic acid (FPA). Formylphosphonic acid can then be reacted with glycine to produce a condensation product which, upon hydrogenation, yields glyphosate. Glyphosate can be incorporated into various formulations for use as a herbicide. In addition to glycine, formylphosphonic acid can also be reacted with ammonia, ethanolamine, or other primary amines to form a precursor compound, which can be converted to glyphosate.

  • Patent number: 5324855
    Abstract: N-acylaminomethylphosphonic acid is prepared from an N-methylolamide compound and a phosphorus trihalide. The starting compounds are mixed and heated in an aprotic solvent in the presence of water in a 0.25 to 2.5 times molar amount relative to the phosphorus trihalide at 60.degree. to 160.degree. C., and the reaction mixture is contacted with water. The N-methylolamide compound is a compound selected from the group consisting of N-methylol-lower alkylamides and N-methylolarylamides. The phosphorus trihalide is preferably phosphorus trichloride. As the aprotic solvent is used one or more of hydrocarbons, halogenated hydrocarbons, ethers, polyethers, nitriles, and aromatic nitro compounds. The mixing may be carried out at a temperature of 60.degree. C. The water present at the initiation of the reaction is in a 1.0 to 1.8 times molar amount relative to the phosphorus trihalide.
