  • Publication number: 20230340338
    Abstract: Described are compositions including a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound. In addition, processes for removing sulfur compounds from process streams using such compositions are described, as well as such processes in which the process stream is contacted independently with a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound. Further described is the use of such compositions to remove sulfur compounds from process streams and the use of a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound to remove sulfur compounds from process streams.

  • Patent number: 10836658
    Abstract: A preparation including a) at least one N-formal and b) at least one dialkylhydroxylamine. The preparation is preferably formulated as a concentrate. The preparation can be used (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.
