Abstract:
The present invention is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. In detail the present invention relates a process comprising bringing a compound of general formula (I) into the gaseous or aerosol state (Fig.) and depositing the compound of general formula (I) from the gaseous or aerosol state onto a solid substrate, wherein R1 and R4 are independent of each other an alkyl group, an aryl group or a trialkylsilyl group, R2, R3, R5 and R6 are independent of each other hydrogen, an alkyl group, an aryl group or a trialkylsilyl group, n is an integer from 1 to 3, M is Ni or Co, X is a ligand which coordinates M, and m is an integer from 0 to 4.
Abstract:
The invention relates to a method for processing a reaction mixture (R G ) containing cyclododecatriene and an active catalyst system (K), which contains an aluminum-organic compound. Said method comprises the following steps: a) the reaction mixture (R G ) is brought into contact with gaseous ammonia to obtain a first mixture (G1); b) the first mixture (G1) is brought into contact with water to obtain a second mixture (G2); c) cyclododecatriene is separated from the second mixture (G2) by distillation.
Abstract:
A process for preparing formic acid by hydrogenation of carbon dioxide in the presence of a tertiary amine (I), a diamine (II), a polar solvent and a catalyst comprising gold at a pressure of from 0.2 to 30 MPa abs and a temperature of from 0 to 200°C, wherein the catalyst is a heterogeneous catalyst comprising gold.
Abstract:
The invention relates to a method for reprocessing a mixture, containing at least one alcohol of general formula (I) R 1 -CH 2 -CH 2 -OH (I) or at least one branched alcohol of general formula (II) R 1 -CH 2 -CHR 1 -CH 2 -OH (II), at least one oil-soluble complex compound of at least one metal of the 8th, 9th, or 10th group of the periodic table of the elements, which is selected from complex compounds that have at least one ligand L 1 that is at least bidentate, at least one coordination site of L 1 being a nitrogen atom, and at least one acid of general formula (III) R 1 -CH 2 -COOH (III) in the form of a salt of said acid, the groups R 1 being selected from C 2 -C 10 alkyl, linear or branched, characterized in that (a) the mixture is treated with water, which can contain an alkali metal hydroxide, (b) which extract/s salts of acid of general formula (III).
Abstract:
The invention relates to a method for producing branched alcohols of general formula (I), the groups R 1 being different or the same and being selected from C 2 -C 3 alkyl, linear or branched, using at least one alcohol of formula (II) R 1 -CH 2 -CH 2 -OH in a homogeneous phase in the presence of at least one base, characterized in that at least one complex compound containing Ru(II) is used, in which the Ru(II) has at least one ligand L 1 , which is at least bidentate, at least one coordination site of L 1 being a nitrogen atom.
Abstract:
A process is proposed for preparing formic acid by reaction of carbon dioxide (1) with hydrogen (2) in a hydrogenation reactor (I) in the presence of a catalyst containing an element from group 8, 9 or 10 of the Periodic Table, of a tertiary amine containing at least 12 carbon atoms per molecule, and of a polar solvent comprising one or more monoalcohols selected from methanol, ethanol, propanols and butanols, and water, to form formic acid/amine adducts as intermediates, which are subsequently cleaved thermally, with workup of the outputs (3) from the hydrogenation reactor (I) in several process steps, a stream (13) comprising tertiary amine from the workup being used as a selective solvent for the catalyst.
