Abstract: The invention relates to a method for the continuous production of methoxyamine hydrochloride by dissociating acetone oxime dimethyl ether with hydrogen chloride and water. The inventive method is characterized by carrying out the dissociation step in a reactor column of less than 20 theoretical steps of separation and adjusting the overhead removal amount to at least 30 % of the quantity supplied.
