摘要： The invention relates to a preparation which comprises a) at least one N-formal and b) at least one dialkylhydroxylamine. The preparation is preferably formulated as a concentrate. The invention further relates to the use of the preparation (in particular in the form of the concentrate) for the reduction of free oxygen and the preservation of water, and also correspondingly additivated water. The mixture of N-formals with dialkylhydroxylamine is not only outstandingly compatible, but considerably improves the activity of dialkylhydroxylamines as oxygen scavengers.
