摘要： The invention relates to a method for the separation of an aqueous reaction mixture arising in the production of hydroxylamine using a catalyst, which contains, amongst other things, solid catalyst particles, into a partial stream enriched in catalyst particles and a partial stream depleted of catalyst particles by cross-flow filtration on an inorganic membrane, characterised in that the mean pore diameter of the inorganic membrane is less than 10 nm.
