  • Patent number: 5728364
    Abstract: There is provided an improved method for making synthetic hydrotalcite by first reacting a divalent metal compound with a trivalent metal oxide powder in a carboxylic acid-free, aqueous solution or suspension to form an intermediate. This intermediate is then contacted with an anion source such as carbon dioxide; a carbonate-containing compound; an acid or an ammonium salt to form a layered double hydroxide having the formula:A.sub.1-x B.sub.x (OH).sub.2 C.sub.z.mH.sub.2 O, where A represents a divalent metal cation, B represents a trivalent metal cation, C represents a mono- to polyvalent anion, and x, z and m satisfy the following conditions: 0.09<x<0.67; z=x/n, where n=the charge on the anion; and 2>m>0.5. Said layered double hydroxide is typically separated from the suspension by filtering, centrifugation, vacuum dehydration or other known means.

  • Patent number: 5665671
    Abstract: A compound for plant defense from parasites, including fungi and bacteria, utilizing lower concentrations of Cu than available Cu-based fungicides. Until now compounds with high Cu concentration have been used, which damage the environment. This compound instead, besides containing Cu in minimal concentration, has a greater stability, due to the particular bond formed between the principal constituents. The compound is thus very valuable in the defense of plants, because it makes possible reducing treatments and it minimizes environmental risks.

    Abstract: A method of treating inflammation or arthritis with metal complexes that can traverse skin and animal cell membranes intact and effectively deliver and release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions. The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration. This dissociation property enables the metal complexes to release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions. The metal complexes can be effectively administered either topically or subcutaneously.

  • Patent number: 4657956
    Abstract: Additives for rubber compositions, giving vulcanizates having improved retention of optimum physical properties, are compounds having the formula R--S--B--S--R where B is an organic bridging group and R is an electron-withdrawing group, for example CN, CCl.sub.3, a radical containing an activated methylene group linked to the sulphur atom or the enolic tautomer of a keto-activated methylene group. Also useful as stabilizing agents are oligomeric analogues of such compounds.

  • Patent number: 4599436
    Abstract: Sodium aurothiomalate used as a therapeutic agent or as a component in a therapeutic agent is shown to be a mixture of substances, one of which is non-toxic to blood platelets, shows specific spectral absorption visibility and does not demonstrate the usual irregular gold containing particles in platelets. As well as being an improvement on the mixture currently employed, the colorless state of sodium aurothiomalate shows promise as an antithrombitic agent.

  • Patent number: 4595773
    Abstract: Copper-diamine complexes such as copper(II)-di-t-butylethylenediamine dibromide are prepared by the reaction of a dihalide such as 1,2-dibromoethane with an amine such as t-butylamine and a basic copper(II) compound such as cupric oxide in a nitrile solvent. The diamine can be liberated from the complex by reacting it with a complexing agent such as an ethylenediaminetetraacetic acid salt.

  • Patent number: 4590255
    Abstract: A process for making metal salt (ionomers) of carboxylic acid-containing mono- and polyether polyol addition products by (1) reacting maleic acid, fumaric acid, itaconic acid, or mixtures thereof with at least one polyhydroxy-containing mono- or polyether compound (e.g. a polyether diol or triol) in the presence of a peroxy-type free radical initiator to form a carboxylic acid group-containing addition product and (2) neutralizing said addition product with a sufficient amount of metal ions selected from the group consisting of metals from Groups 1a, 2a, 8, 1b and 2b of the Periodic Table to convert at least about 10% of the carboxylic acid groups to ionomeric salt groups. These ionomers may be then changed into useful polyurethane elastomers by reaction with organic polyisocyanates.
