Abstract

An improved oxygen scavenger for aqueous mediums is disclosed which is a hydroxyalkylhydroxylamine. The material may be catalyzed with a compound such as copper, hydroquinone, benzoquinone, 1,2-naphthoquinone-4-sulfonic acid, pyrogallol and t-butylcatechol. Hydroxyalkyl substituted hydroxyalmines of the general formula HO-N-[CH.sub.2 --CH(OH)--R].sub.2 wherein R is H or C.sub.1 to C.sub.10 alkyl have been found to be effective oxygen scavengers for aqueous systems such as industrial water system.
