Abstract: A process for preparing a salt-free aqueous hydroxylamine solution by reacting an aqueous solution of a hydroxylammonium salt with a base to give a mixture and separating from said mixture by distillation a salt-free aqueous hydroxylamine solution, involving using as a base an aqueous solution of a mixture of NaOH and KOH in a molar ratio Na + :K + in the range from 70:30 to 95:5 and with a total concentration of Na + and K + in the range from 0.1 to 10 m/m % based on the total amount of the mixture.

Abstract: The invention relates to a method for producing a highly pure, aqueous hydroxylamine solution by distilling an aqueous solution, devoid of salt, of a hydroxyl ammonium salt in a plate column comprising at least two mechanical plates. Said method is characterised in that packing bodies are arranged between at least two plates of the plate column over the cross-section of said column.

Abstract: A method for the production of aromatic di-isocyanates (I) by gas-phase reaction of phosgene with diamines involves carrying out the reaction in a reaction zone under a pressure of more than 3 bar and less than 20 bar. An Independent claim is also included for a production unit for this process, in which the ratio of production capacity to phosgene hold-up is more than 3200 tonnes di-isocyanate per annum/kg phosgene.

Abstract: A method for the production of formaldehyde by gas phase oxidation of methanol vapour with a gas flow containing a molecular oxygen in the presence of solid bed catalyst containing iron and molybdenum is carried out in a reactor (1) comprising thermal sheet metal plates (2) which are arranged in the longitudinal direction of the reactor (1) and spaced from each other. A heat transfer medium flows through the gaps between the plates. The heat transfer medium is transferred via inlets and outlets 3, 4 to the thermal sheet steel plates (2), and gaps (5) between the thermal sheet steel metal plates (2) and which are filled with the solid bed catalyst and into which the gas containing the methanol vapour and the molecular oxygen flows.
