Preparation of O-substituted hydroxylammonium salts of the formula I H2NOR x HX I where R is a C1-C6-alkyl or C2-C6-allcenyl radical, each of which may be halogen-substituted, and X is chlorine or bromine, by reacting in an integrated process, without isolation of inter- mediates a) acetone with hydroxylammonium sulfate and sodium hydroxide solution to give acetone oxime; b) treating the solution of acetone oxime thus obtained with sodium hydroxide solution and completely removing water, c) reacting the suspension of the acetone oxime Na salt thus ob- tained with alkylating agents at from 0.5 to 15 bar and at up to 140°C to give acetone oxime ethers; and d) cleaving the acetone oxime ethers with acids HX to give the products I, a homogeneous, nonpolar aprotic solvent being used in all process steps a) to d).
