Abstract: In the production of 6-30C aldehydes and/or alcohols (A) by hydroformylation, the reaction mixture (olefins, synthesis gas and catalysts, or their precursors) is introduced into the reactor through a nozzle with adjustable transmission cross-section. Reaction is at 120-210 deg C and 100-400 bar and the reaction mixture is introduced at high speed into a high-pressure reactor. An Independent claim is also included for a reactor for production of (A) by the new process.

Abstract: Process for the preparation of methyl formate by reaction of methanol on copper-containing catalysts at elevated temperature and in the gas phase by using a catalyst containing, apart from 30 to 80% by weight of copper, calculated as CuO, 20 to 70% by weight of magnesium silicates, calculated as MgO plus SiO2 in which the MgO/SiO2 molar ratio is 0.3 to 1.5, and which can be additionally doped with the metals zinc, chromium and/or barium in amounts of, in each case, up to 1.5% by weight, calculated as ZnO, Cr2O3 and BaO.

Abstract: The invention relates to a method for hydroformylating olefins having between 20 and 400 carbon atoms by reacting the olefins with synthesis gas in the presence of a cobalt carbonyl catalyst, by recovering the cobalt catalyst by extracting the discarded substances resulting from the reaction using an aqueous acidic solution in the presence of oxygen, and by separating the organic and aqueous phases. The inventive method is characterized in that: (a) the aqueous phase is separated away from the organic phase to the greatest possible extent by using mass forces such that the proportion of the aqueous phase dispersed in the organic phase is equal to 2 wt. % or less with regard to the organic phase, and; (b) the organic phase involved in step (a) is subjected to an electric field while effecting the coalescence of the dispersed aqueous phase. This enables the residual cobalt content in the hydroformylation product to be reduced to less than 1 ppm.
