  • Patent number: 8957235
    Abstract: This disclosure provides a process for making transition metal carboxylate compositions by combining in an polar aprotic first solvent a transition metal precursor and a Group 1 or Group 2 metal carboxylate under substantially acid-free and substantially anhydrous conditions, to generate a mixture comprising the transition metal carboxylate composition. Optionally, the transition metal carboxylate composition can be purified, for example, by substantially removing the first solvent provide a residue comprising the transition metal carboxylate composition, and also optionally, further by extracting the transition metal carboxylate composition from the residue with a non-coordinating second solvent to provide an extract comprising the transition metal carboxylate composition.

  • Patent number: 8389755
    Abstract: A gas adsorption material has a three-dimensional structure wherein a ligand (p-hydroxybenzoic acid) having an aromatic ring as a principal skeleton containing, a carboxyl group and a functional group capable of forming a coordinate bond, the functional group being other than the carboxyl group, and a metal nucleus (Zn) are bonded to each other at a ratio of 1:1. The ligand contains a functional hydroxyl group other than the carboxyl group, and the carboxyl group and the functional group other than the carboxyl group are bonded in at least one position to the metal nucleus. The gas adsorption material is produced by drying a precursor obtained by reacting the ligand and the metal nucleus, dissolving the dried precursor in an organic solvent, heating and stirring a resultant solution to form a three-dimensional structure that includes the organic solvent as a crystal solvent, and removing the crystal solvent.

    Abstract: A dietary source of mineral in the form of a metal carboxylate is prepared using the acid-base-like reaction. A salt of a carboxylate anion and a by-product cation is reacted in aqueous solution with a salt of a metal cation and a by-product anion under conditions which form a metal carboxylate and the by-product salt. Solutions formed in the reaction may be applied directly to a dry carrier to produce a dry dietary supplement or, alternatively, the solutions may be filtered to remove precipitated by-product salt and the filtrate used as a liquid dietary supplement. Preferably, a reducing agent, such as ascorbic acid, is added to help prevent the oxidation of divalent to trivalent form of a metal salt, when an easily oxidized divalent metal is used as starting material.

  • Patent number: 5457218
    Abstract: Electrochromic coating solutions are prepared by reacting a transition metal with a mixture of hydrogen peroxide and an organic acid. The resulting transition metal-peroxy acid product is esterified by reacting with lower carbon alcohols to produce a peroxyester-transition metal derivative. This derivative in solution in lower carbon alcohols provides a working solution into which a substrate having a conductive surface is preferable dipped and removed at a rate sufficient to give a coating of a desired thickness over the conductive surface. Spray or spin coating can be used to apply the coating to the conductive surface of the substrate. The coating is then dried and is externally fired in an oven to complete the necessary reactions to yield an electrochromic oxide coating having exceptional electrochromic properties.
