Abstract: Pitting corrosion of stainless steel occurs in solutions of organic acid, such as tartaric acid, in an electrolyte solution with methanol. However, methanolic solutions containing at least one organic halide and at least one organic hydroxyacid and some water provide reduced pitting corrosion of stainless steel. The organic hydroxyacid may be a hydroxy acid containing 2 to 10 carbon atoms with at least one hydroxyl group and at least one carboxylic acid group, in a non-limiting example, glycolic acid. The pH of the methanolic solution may range from about 3.5 to about 8.

Abstract: This invention is directed to a method of inhibiting corrosion-erosion in pipelines carry slurries. The method includes contacting for a period of at least 1 hour an inner surface of the pipeline with a composition of matter, the composition being at least one corrosion inhibitor within a water solvent, purging the pipeline of the water, and then transporting a slurry through the pipeline. This method is surprisingly effective because it prevents erosion with materials that were previously known to not have any effect on erosion. In addition it is effective on especially hard slurries such as bauxite for which previous uses of these inhibitors did not prevent erosion.
