1,2-dithiolium compounds as corrosion inhibitors
摘要:
1,2-dithiolium compounds are prepared by oxidizing 1,2-dithiole3-thiones. In general, aliphatic-substituted dithiolium compounds have been found to be more stable and more water-soluble than aryl-substituted dithiolium compounds. Dithiolium compounds are useful as corrosion inhibitors in aqueous and/or aerated and/or acidic systems. Their usefulness as corrosion inhibitors is enhanced by the high water solubility and stability of the aliphatic-substituted dithiolium compounds.
