Abstract
Process for the preparation of n, 0-dialkylhydroxylamines, characterized in that a) in a first step a hydroxylamine, a hydroxylamine salt or a hydroxylamine disulfonate is reacted with an aldehyde or a ketone, The formed oximinic compound is reacted with an alkylating agent, c) in a third step the reaction product obtained in the previous step is quaternized, excluding moisture and in the temperature range of 50 to 140º c, with an alkylating agent, forming a respective N-alkylidene-n, O-dialkylammonium salt of the formula ** (see formula) ** In which Z means the anionic radical from the quaternization agent and one of the substituents Alkyl'or alkyl' means the alkyl radical introduced first, while the other means the alkyl radical introduced during quaternization And d) in a fourth step of the reaction, the above-described complex salt is hydrolyzed in an acid medium.
