Abstract
A method for boiler water treatment to retard corrosion due to dissolved oxygen. Hydroquinone and certain related compounds are highly effective oxygen scavengers for use in boiler water and thereby effect reduction of corrosion resulting from dissolved oxygen.
Claims5
A method for control of corrosion of metal surfaces in a boiler system caused by dissolved oxygen in the water, which comprises adding to the said system an effective amount, from 0.1 to 20 parts by weight per part of the oxygen in the water of an oxygen scavenger selected from the group consisting of ##STR2## in which R and R.sub.1 are independently selected from the group consisting of --OH or --NH.sub.2 ;
- R.sub.2 (when present) is lower alkyl containing 1-8 carbons:
- M is H, Na, or K:
- and combinations thereof;
- said group member being the sole oxygen scavenger present.
