Abstract
A process for the preparation of a hydroxylammonium slat and an oxime from said hydroxylammonium salt and an aldehyde or keton is disclosed in which an aqueous acid reaction medium is kept in circulation between a zone for the synthesis of the salt and a zone for the synthesis of the oxime and in which nitrate ions and/or nitrogen monoxide are continuously supplied as a reducible nitrogen source for the liquid kept in circulation, wherein the circulation liquid is subjected to an electrodialysis to remove the ammonium ions formed as a byproduct in the hydroxylammonium salt synthesis.
