摘要： A liquid composition comprising a high-capacity aqueous carrier in which (i) a metalloid compound selected from the group consisting of antimony and germanium compounds and (ii) morpholine or derivative thereof are dissolved in the presence of (iii) unsaturated alcohol and (iv) water-soluble organic acid having reducing capacity, wherein the total concentration of said four components is not less than 5% relative to the total weight of the composition. The composition is useful as a corrosion inhibitor. Also provided is a process for preparing the composition.

摘要： Provided is an anticorrosive composition for use in aqueous salt solutions. The composition contains an antimony compound and at least two other components selected from morpholine derivatives, acetylenic alcohols, ascorbic acid derivatives, and selenium compounds. The composition is particularly useful for inhibiting corrosion of metallic surfaces of drilling devices or refrigeration systems that are in contact with salt brines at elevated temperatures.
