摘要： The invention relates to a method for the production of a salt-free aqueous hydroxylamine solution by distilling an aqueous solution of an hydroxylammonium salt and a base in a plate column having at least two mechanical plates. The invention is characterized in that packings or structured packings are placed above at least one of the plates of the plate column along the cross section of said column.

摘要： The invention relates to a method for producing an aqueous hydroxylamine solution that is devoid of salt by reacting an aqueous solution of a hydroxylammonium salt with a base to obtain a mixture and by separating an aqueous hydroxylamine solution devoid of salt by distillation from said mixture. The method is characterised in that an aqueous solution of a mixture of NaOH and KOH with a molar ratio of Na+: K+ in the region of between 70: 30 and 95: 5 and a total concentration of Na+ and K+ in the region of between 0.1 and 10 m/m % (in relation to the total quantity of the mixture) is used as the base.

摘要： 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.
