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.

The composition is preferably used in the removal of hydrogen sulphide from process streams.

Abstract: The invention relates to a preparation comprising a) 10 to 80% by weight of ?,??,??-trimethyl-1,3,5-triazine-1,3,5-(2H,4H,6H) triethanol (TTT) and b) one or more additives selected from i) ammonia, ii) alkanolamines with primary amino group and alkyl group having at most eight carbon atoms and iii) alkylamines with primary amino group and alkyl group having at most eight carbon atoms, where the weight ratio a):b) is in the range from 100:30 to 100:1. The preparation is present as semi-concentrate and has an advantageously lower viscosity, is moreover storage-stable, in particular storage-stable over a long period.

Abstract: Disclosed is a storage-stable condensation product prepared from 1-amino-2-propanol and formaldehyde in a molar ratio in the range from 1:2.0 to 1:3.1. The condensation product contains less than 10% by weight of water. Also, disclosed is the preparation of the condensation product and the use thereof for reducing the amount of hydrogen sulphide in liquids and gases.

Abstract: The invention relates to the use of a composition that comprises a) one or more condensation products of 1-amino-propan-2-ol and formaldehyde and b) monoethylene glycol, wherein component a) is present in an amount from 5 to 70% by weight and component b) is present in an amount from 30 to 95% by weight, in each case based on the weight of the composition, in the removal of sulphur compounds from process streams.
