Abstract: There is provided a method for the production of hydroxylamine derivatives or the salt thereof in which a salt of hydroxamic acid is reacted with an alkylating agent such as diethyl sulfate to form an ester of hydroxamic acid, which is reacted with mineral acid in an aqueous solution of lower alcohol so as to prepare hydroxylamine derivatives or the salt thereof. In this process, the incorporation of an oxidizing agent or aldehydes in the reaction system will significantly reduce the content of nitrosoamines in the resulting solution of hydroxylamine derivatives or the salt thereof. Therefore, the resulting hydroxylamine derivatives obtained with a lesser content of harmful compound will be useful as an intermediate for the production of drugs and pesticides.
