Abstract
An oxygen-scavenging and corrosion-inhibiting agent for fluidic systems comprising an aminoguanidine compound selected from the formula: ##STR1## or a salt thereof, wherein R is selected from H or a lower alkyl group having 1 to 4 carbon atoms; wherein X is selected from NH or NNH.sub.2 ; and Y is selected from --NH.sub.2 or --NHNH.sub.2.
Claims11
A method for scavenging oxygen and for protecting metal surfaces against corrosion caused by contact of an oxygen-containing fluid therewith comprising adding an effective amount of an aminoguanidine compound to scavenge at least a portion of the oxygen contained therein and to inhibit corrosion on the metal surfaces in contact therewith;
- said aminoguanidine compound selected from the formula ##STR14## or a salt thereof;
- wherein R is selected from H or a lower alkyl group having 1 to 4 carbon atoms;
- wherein X is selected from NH or NNH.sub.2 ;
- and Y is selected from --NH.sub.2 or --NHNH.sub.2.
