    摘要: The present invention relates to a method for producing dialkylamides of the alkali metals by reacting the corresponding dialkylamine with the corresponding alkali metal in the presence of an electron donor substance of the group 1,3-butadiene, isoprene, naphthalene and/or styrene with the formation of low quantities of butenyl dialkylamine. According to said method, the corresponding alkali metal is introduced and suspended in a solvent and the dialkylamine and the electron donor substance are added, such that the dialkylamine is present in an amount up to 45 wt. %, preferably up to 25 wt. %, in particular up to 15 wt. % and the butadiene is present in an amount up to 5 wt. %, preferably up to 3 wt. %, in particular up to 1.5 wt. %.

    摘要: A process for producing aldehydes by the hydroformylation of olefins with more than 3 carbon atoms, comprising the hydroformylation stage by means of a rhodium catalyst uniformly dissolved in the reaction medium, the separation of the rhodium catalyst from the product from the hydroformylation reaction and its return to the hydroformylation stage, in which the rhodium catalyst is extracted into the aqueous phase by means of an aqueous solution of a nitrogen-containing complexing agent from the group of sulphonated pyridines, sulphonated quinolines, possibly substituted sulphonated or sulphonated component-containing 2,2' bipyridines, 1,10 phenanthrolines, 1,1' biquinolines, 2,2', 6', 2'' terpyridines and porphines, and/or from the group of carboxylated pyridines, carboxylated quinolines, possibly substituted, carboxylated or carboxylated substance-containing 2,2' bipyridines, 1,10 phenanthrolines, 2,2' biquinolines, 2,2', 6', 2'' terpyridines and porphines, and the alcohol and/or aldehyde is isolated and from the extracted hydroformylation product, the aqueous rodhium-containing extract is taken to a pre-carbonylation stage and subjected to a pre-carbonylation in said stage in the presence of a substantially water-soluble organic fluid and in the presence of carbon monoxide, synthesis gas or a carbon monoxide-containing gas mixture at a pressure of 50 to 100 bars and a temperature of 50 to 180 DEG C, the product from the pre-carbonylation stage is separated into an organic part containing the majority of the rhodium and an aqueous phase containing the complexing agents and the organic phase for the hydroformylation of the olefin is taken to the hydroformylation stage at 50 to 100 bars and a temperature of 50 to 180 DEG C.

    摘要: Aliphatic alpha,omega-aminonitriles are prepared by partially hydrogenating aliphatic alpha,omega-dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The catalyst contains (a) a compound based on a metal selected from the group made up of nickel, cobalt, iron, ruthenium and rhodium; (b) 0.01 to 25 % by weight in relation to (a) of a promoter based on a metal selected from the group comprising of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminium, tin, phosphorus, arsenic, antimony, bismuth, silicium, titanium, zirconium and rare earth metals; and (c) 0 to 5 % by weight in relation to (a) of a compound based on an alkaline or alkaline-earth metal, provided that component (a) not be based on iron or iron and a metal selected from the group comprising cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group comprising titanium, manganese, chromium and molybdenum. Moreover, when component (a) is a compound based only on ruthenium or on rhodium, ruthenium and rhodium, or nickel and rhodium, promoter (b) may be dispensed with.
