Abstract
The reaction of propargyl alcohol and iodine gives 2,3di-iodo-2-propen-1-ol, and it has been discovered that this compound is effective as an intermediate in a corrosion inhibitor for metals in acid media, particularly halogen acids. The compound provides iodine to the media in a stable form that does not appear to degrade over time.
