New oxygen scavengers for boiler waters have been discovered, which oxygen scavengers are based upon substituted quinoline compounds. These compounds provide oxygen scavenging capabilities, metal passivating capabilities, and volatility such that condensate systems in an operating boiler are protected. The compounds may be formulated with other oxygen scavengers and other common treatment agents used in boiler waters, especially the volatile amine, such as, but not limited to, morpholine and diethylhydroxylamine. The preferred quinoline compounds is ethoxyquin, i.e. 6-ethoxy-1,2,-dihydro-2,2,4-dihydroquinoline.
