  • Method of making phosphorus-containing compounds and products thereof
    Patent number: 6864218
    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.

  • Organic phosphorus-inorganic phosphorus oxyacids compounds and compositions
    Patent number: 6545073
    Abstract: A flame retardant composition is produced by mixing a flammable organic material with an organic phosphorus-inorganic phosphorus oxyacid compound or its salts. The organic phosphorus-inorganic phosphorus oxyacid compounds are produced by reacting an organic phosphorus compound with an inorganic phosphorus oxyacid. The organic phosphorus-inorganic phosphorus oxyacid compound may be reacted with a basic salt forming compound. The flammable organic material such as thermoplastic resins are made less flammable by melting-kneading the flammable material with the organic phosphorus-inorganic phosphorus oxyacid compound or it's basic salt, carbonization auxiliaries, a metal-containing compound having a carbonization acceleration effect, a comb-like polymer and a filler.
