Title:

OXIDATION INHIBITOR OF STEEL AND AQUEOUS COMPOSITION CONTAINING THE SAME

Document Type and Number:

Japanese Patent JPS63286590

Kind Code:

A

Abstract:

Corrosion inhibitors especially for carbon- or low-alloy steels. They are ternary mixtures, with synergetic activity, containing, in molar percentages, approximately: from 62 to 98 % of strong base, from 0.23 to 9.5 % of arsenic trioxide, from 1.45 to 33 % of compounds chosen from benzotriazole, its derivatives and their mixtures. Aqueous alkali metal halide compositions containing the said inhibitors are also claimed. Such compositions can be employed as working fluids in high-temperature absorption heat-pump devices.
