Abstract:
The present invention relates to methods for producing a porous, organometallic framework material containing a first and at least one second at least bidentate organic compound coordinatively bound to at least one copper ion, including the following steps: (a) Reaction of a reaction mixture in the liquid phase containing at least one copper compound and the first at least bidentate organic compound with formation of a complex intermediate containing at least one copper ion and the first at least bidentate organic compound, wherein the first at least bidentate organic compound derives from a dicarboxylic acid and has a hydrocarbon framework, and (b) Reaction of the complex intermediate with the at least second at least bidentate organic compound, wherein the at least second at least bidentate organic compound is an optionally substituted monocyclic, bicyclic or polycyclic saturated or unsaturated hydrocarbon in which at least two ring carbon atoms are replaced by heteroatoms selected from the group consisting of N, O and S, wherein the reaction mixture in step (a) has less than a threefold excess amount of 25 formic acid based on the copper used in the copper compound.
Abstract:
The present invention relates to a process for preparing a porous metal organic framework comprising at least two organic compounds coordinated to at least one metal ion, which comprises the steps (a) oxidation of at least one anode containing metal corresponding to the at least one metal ion in a reaction medium in the presence of at least a first organic compound, where the first organic compound is an optionally substituted monocyclic, bicyclic or polycyclic saturated or unsaturated hydrocarbon in which at least two ring carbons are replaced by heteroatoms selected from the group consisting of N, O and S, to form a reaction intermediate containing at least one metal ion and the first organic compound; and (b) reaction of the reaction intermediate at a prescribed temperature with an at least second organic compound which coordinates to the at least one metal ion, where the second organic compound is derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid.
Abstract:
The invention relates to methods for producing a porous metal-organic framework material which contains at least one at least bidentate compound that is coordinately bound to at least one metal ion. Said method comprises the step of reacting at least one metal compound with at least one at least bidentate organic compound which is capable of coordinately binding to the metal. The metal ion of the at least one metal compound is selected from the group of metals including titanium, zirconium, and hafnium. The at least bidentate compound is derived from a di-, tri- or tetracarboxylic acid and the metal compound is an inorganic salt.
Abstract:
The invention relates to a porous metal-organic framework material, containing at least one organic bidentate compound that is coordinately bound to at least one metal ion, the at least one metal ion being zirconium and the at least one at least bidentate organic compound being derived from a di-, tri- or tetracarboxylic acid. The invention also relates to methods for producing said materials and to the use thereof.
Abstract:
The invention relates to a method for producing an organometallic building material, comprising reacting, in the presence of a base and a solvent, a fluid mixture that contains a metal salt having at least one bidentate organic compound capable of coordination with metal ions, said solvent containing at least one cyclic amide (lactam) and/or at least one cyclic ester (lactone).
Abstract:
The invention relates to a moulding compound, comprising between 10 and 99.999 wt. % of at least one polyoxymethylene as component (A1) and between 0.001 and 10 wt. %, (in relation to the weight of the component (A1) contained in the moulding compound), of at least one zeolitic material with a pore diameter ranging between 0.3 and 0.5 nm, determined according to the DIN 66134 and DIN 66135 standards. The size of the particles of zeolitic material ranges between 3 and 7 ?m, determined according to the ISO 13320 standard. The invention also relates to moulded bodies that are produced from said moulding compound.
Abstract:
The invention relates to a method for hydrogenating an organic compound, which has at least one carbonyl group, during which the organic compound is, in the presence of hydrogen, brought into contact with a shaped body that can be produced according to a method in which: (i) an oxidic material comprising copper oxide and aluminum oxide and at least one of the oxides of iron, lanthanum, tungsten, molybdenum, titanium, zirconium, tin or manganese, as well as, optionally, tin oxide and/or manganese oxide; (ii) powdered metallic copper, copper flakes, powdered cement, graphite or a mixture thereof is added to the oxidic material; (iii) the mixture resulting from (ii) is shaped into a shaped body, and; (iv) the shaped body is treated with water or steam.
