<p>An oxygen scavenger which is highly effective in deoxidizing under a wide range of conditions and is useful as a volatile oxygen scavenger as a hydrazine substitute. The oxygen scavenger comprises a heterocyclic compound having an N-substituted amino group, e.g., 1-amino-4-methylpiperazine, and a hydroxyamine compound, e.g., N,N-diethylhydroxyamine. It may further contain a polyhydric phenol catalyst, e.g., pyrogallol. When added to the water to be supplied to the water system of, e.g., a boiler, the oxygen scavenger deoxidizes the aqueous system.</p> |
