Provided is a process by which O-substituted hydroxyl- amines can be produced from industrially available raw materials in high yield, namely, a process for the production of O-substituted hydroxylamines which comprises the step of reacting an alkali metal salt of hydroxylaminedisulfonic acid with a halide such as an alkylating agent (RX) to form an alkali metal salt of an O- substituted hydroxylaminedisulfonic acid and the step of hydrolyzing the alkali metal salt obtained in the preceding step.

L'invention concerne un procédé qui permet de produire des hydroxylamines O-substituées à partir de matières premières disponibles au niveau industriel à un rendement élevé. D'une manière plus spécifique, l'invention concerne un procédé permettant de produire des hydroxylamines O-substituées qui consiste à faire réagir un sel métallique alcalin d'acide hydroxylaminedisulfonique avec un halogénure, tel qu'un agent d'alkylation (RX) afin de former un sel métallique alcalin d'un acide hydroxylaminedisulfonique O-substitué et à hydrolyser le sel métallique alcalin obtenu lors de l'étape précédente.
