  • Patent number: 6441223
    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: 5635608
    Abstract: The invention relates to caged compounds for the study of biological processes, where the caged compound has a photoremoveable .alpha.-carboxy-substituted o-nitrobenzyl group. Covalent attachment of the substituted o-nitrobenzyl to a parent compound yields a caged compound with biological and/or physical properties that are significantly altered from the original properties of the parent compound. Illumination of the caged compounds to cleave the photoremoveable group yields the parent compound with its original properties restored.

  • Patent number: 5407969
    Abstract: The invention relates to acyl-(2'-hydroxydiphenyl-2-yl)-phosphinic acid salts of formula (I) ##STR1## in which each of the radicals R.sup.1, R.sup.2 and R.sup.3 may be included singly or multiply and in which R.sup.1 and R.sup.2 are mutually independently hydrogen, an alkyl or alkoxy radical with 1 to 6 carbon atoms or halogen with an atomic number of 9 to 35; R.sup.3 means the same as R.sup.1 or R.sup.2 ; Ar is an aromatic hydrocarbon radical with 6 to 10 carbon atoms; and Me is a cation of at least one alkaline metal or N(R.sup.4).sub.4 + in which the radicals R.sup.4 are the same or different and stand for an alkyl radical with 1 to 6 carbon atoms. The invention also relates to a process for producing these compounds (I) and their use as photoinitiators in photopolymerisable materials, preferably on an aqueous basis.

  • Patent number: 5376731
    Abstract: Phosphonic (co) telomers of the type described in U.S. Pat. Nos. 4,046,707 and 4,681,686 and European Patent Application 360746 may be produced by an aqueous process comprising (a) reacting hypophosphorous acid with a carbonyl compound which is preferably an aldehyde, a ketone or an imine, (b) reacting the product of (a) with an olefin or olefins in the presence of a suitable initiator especially a free radical initiator, and (c) converting the product obtained from (b) to a phosphonic (co) telomer, e.g., by reaction with hypochlorite. The (co) telomer products are useful as scale inhibitors in aqueous systems.
