詳細

詳細

The product is a 70% aqueous solution of methanesulfonic acid (MSA). MSA is a strong organic acid. The chemical oxidation of dimetyl sulfide in the atmosphere leads to the formation of MSA in large quantities. MSA undergoes biodegradation by forming CO₂ and sulphate. It is considered a green acid as it is less toxic and corrosive in comparison to mineral acids.1 The aqueous MSA solution has been considered a model electrolyte for electrochemical processes.

アプリケーション

Methanesulfonic acid solution may be used to study the corrosion behavior of stainless steel.
