Abstract: Poly(alkylene oxide) compositions are provided which exhibit excellent resistance to oxidative degradation and inhibit the corrosion of ferrous metals, which compositions have incorporated therein an effective amount of a mononuclear aromatic compound having at least one substituent nitro group.

Abstract: Poly(alkylene oxide) compositions are provided which exhibit excellent resistance to oxidative degradation and inhibit the corrosion of ferrous metals, which compositions have incorporated therein a small effective amount of a bridged dimer of a hydroxyl-substituted aromatic carboxylic acid and salts thereof of the general formula: ##STR1## wherein X is a chemically stable group selected from lower alkylene, sulfonyl, and amino groups, and a sulfur atom, and Y and Y' may be the same or different, and are a hydrogen atom, hydroxyl group, amino group, alkyl group, or sulfonyl group.

Abstract: Corrosion of metallic surfaces by aqueous alkanolamine solutions employed in acid gas removal service can be inhibited by combinations of antimony and vanadium compounds, stannous salts, organo-tin compounds, nitro aromatic acids and their salts or benzotriazole.

Abstract: Corrosion inhibition of ferrous metals by aqueous potassium carbonate solutions in acid gas treating systems is effected by a combination of antimony compounds with vanadium anions in the plus 5 valence state.
