    摘要： Preparation of O-substituted hydroxylammonium salts of the formula IH.sub.2 NOR x HX Iwhere R is a C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl radical, each of which may be halogen-substituted, and X is chlorine or bromine, by reacting in an integrated process, without isolation of intermediatesa) 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 obtained with alkylating agents at from 0.5 to 15 bar and at up to 140.degree. C. to give acetone oxime ethers; andd) 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).
