  • Publication number: 20120046483
    Abstract: A catalyst for esterification and polyesterification is proposed. The catalyst is an iron acetylacetonate complex having a formula of Fe(RCOCH2COR)3, where R is methyl or a substituent other than methyl. A method for making an esterified product or a polyesterified product by using the iron acetylacetonate complex through esterification and polyesterification is also disclosed so as to improve the existing processes where hydrochloric acid or sulfuric acid used as the catalyst causes yellowed products, danger operation and environmental pollution.

  • Patent number: 7994142
    Abstract: The invention relates to agents that contain folic acid, vitamin B6 and vitamin B12, and to the use thereof in hyperhomocysteinemia for controlling homocysteine levels. The agents are mainly suitable for the preventive and acute treatment of vascular diseases, of pregnant women and neurodegenerative diseases and are particularly advantageous in cases where the homocysteine levels to be controlled are found in an individual suffering from renal failure or being treated with immune suppressors. The invention particularly relates to pharmaceutical agents and food supplements comprising a corresponding active ingredient combination and to agents in the form of commercial packages containing corresponding combination preparations or monopreparations for the combined use.

  • Publication number: 20110172412
    Abstract: The present invention relates to reducible porous crystalline solids, constituted of a metal-organic framework (MOF), for the separation of mixtures of molecules having different unsaturation degrees and/or a different number of unsaturations with a selectivity that can be adjusted by controlling the reduction of the MOF. The MOF solids of the present invention, after reduction, have a strong affinity for molecules containing at least one unsaturation. They can be used in various separation processes, especially those relating to hydrocarbons.

  • Patent number: 7968487
    Abstract: Novel phosphine-free non-ionic single catalysts, and method for making such catalysts, for the homo-polymerization and copolymerization of olefins such as ethylene, ?-olefins and functionalized olefins without the use of additional co-activators, are disclosed. These phosphine-free non-ionic single catalysts are also active for co-polymerization of olefins with monomers with polar functionalities. The catalyst of this invention comprise of a late transition metal with a chelating monoanionic ligand, an R group and a neutral 2 electron donor ligand. Catalysts are prepared by the oxidative addition of benzylhalide (halide=Cl, Br or I) to an appropriate metal source in the presence of a stabilizing agent, such as nitrogen based ligands, followed by the addition of the deprotonated form of the chelating ligand.

  • Publication number: 20100284860
    Abstract: An article is provided for immobilizing functional organic biomolecules (e.g. proteins, DNA, and the like) through a covalent bond to a thiolate or disulfide monolayer to a metal surface wherein an extra activation step of the surface layer or an activation step of the functional biomolecules or bioreceptors could be avoided. The monolayer can contain, but is not limited to, two moieties. One has a group that resists nonspecific adsorption and another has a group that directly (without activation) reacts with functional groups on the biomolecules. In addition, poly(ethylene oxide) groups are incorporated in the monolayer surfaces to resist the nonspecific adsorption and to enhance the specific affinity interactions. A sensor device including these monolayers is also provided to perform reproducible, sensitive, specific and stable bioanalysis.

  • Publication number: 20100176031
    Abstract: Crystals of [VOBDC](H2BDC)0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.
