In one embodiment, the method includes the steps of providing a polymer Schiff base transition metal film precursor having a chemical structure of the formula [M(Schiff)]n and a recurring unit and a transition metal selected from the group consisting of nickel, palladium, platinum, cobalt, copper, iron; Schiff is a tetradentate Schiff base ligand selected from the group consisting of Salen (residue of bis(salicylaldehyde)-ethylenediamine), Saltmen (residue of bis(salicylaldehyde)-tetramethylethylenediamine, Salphen (residue of bis-(salicylaldehyde)-o-phenylenediamine), a substituent in a Schiff base is selected from the group consisting of H—, and carbon-containing substituents, preferably CH3—, C2H5—, CH3O—, C2H5O—, and Y is a bridge in a Schiff base depositing the polymer Schiff base transition metal precursor film onto a support substrate; and heating the polymer Schiff base transition metal precursor film and support substrate in a furnace in an inert atmosphere.
摘要:
A method of electrochemically preparing a crystalline, porous, metal-organic framework material comprising at least one at least bidentate organic compound coordinately bound to at least one metal ion, in a reaction medium comprising the at least one bidentate organic compound, wherein at least one metal ion is provided in the reaction medium by the oxidation of one anode comprising the corresponding metal.
摘要:
The present invention relates to a method of absorbing and/or storing gases, in which the gas to be stored is brought into contact with an electrochemically prepared metal-organic framework under conditions suitable for absorption of the gas, with absorption of the gas into the metal-organic framework occurring, and, if appropriate, the conditions are subsequently changed so that release of the stored gas occurs.
摘要:
The present invention relates to a method for separating off odor substances from gases, comprising gas with at least one filter comprising a porous metal-organic framework material, the framework material comprising at least one, at least bidentate, organic compound which is bound by coordination to at least one metal ion.
摘要:
The invention relates to a micro-engineered reactor device comprising a closely coupled reactor and electrochemical cell, and a method of using such a reactor for the synthesis of organic compounds by a process involving an electrochemical reaction. The synthetic processes are of a type in which a source material is electrochemically converted to a reactive primary product which is exposed at a reaction region within a channel, or chamber, to a precursor material so that the primary product and precursor material react to generate a secondary product.
摘要:
The method of continuously monitoring the concentration of Grignard reactant in the "Freeport Process" cell for producing organolead compounds which comprises utilizing a reference half cell consisting of an electrode in anhydrous ether solution with a platinum group sample electrode in a solution of process Grignard reactant and adjusting upwardly the concentration of Grignard when it falls below a value of 0.02M. Also included in the invention are preferred reference half cells utilizing lead and zinc in anhydrous solvent selected from glycol diethers, such as diethylether of tetraethylene glycol (DETEG) and optionally tetrahydrofuran (THF) as a stripping solvent.
摘要:
A process for the synthesis of organonickel derivatives by electrochemical reduction of a nickel(II) complex followed by addition of a haloorganic compound which yields a different nickel(II) complex. The complexes have utility as catalysts for olefin dimerization.
摘要:
A process for the cathodic alkylation of lead using ethyl chloride, methyl chloride, or mixture thereof as an alkylating agent and iodide ion as an electrochemical catalyst with a liquid-liquid junction of propylene carbonate and water wherein propylene carbonate is in the catholyte and water is in the anolyte.
摘要:
A PROCESS FOR THE PREPARATION OF ORGANOMETALLIC COMPOUNDS COMPRISING CONTACTING AN ACTIVATED OLEFIN OR DIARYL-CONTAINING HYDROCARBON WITH AN ELECTRIC CURRENT IN THE PRESENCE OF AN ALKALI OR ALKALINE EARTH METAL SALT ELECTROLYTE, AND A TETRAALKYL SUBSTITUTED UREA, TETRAALKYL SUBSTITUTED THISOUREA, TETRAALKYL SUBSTITUTED SULFONAMIDE OR A HEXAALKYL OR ARYL SUBSTITUTED PHOSPHORAMIDE POLAR SOLVENT.
