General description
Methanesulfonic acid (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.
Application
Methanesulfonic acid may be used:
• As a catalyst to produce linear alkylbenzenes by the addition reaction between long-chain olefins and benzene.
• To prepare polyaniline (PANI)/graphene composites with enhanced thermal and electrical properties.
• As a catalyst for the transformation of glucose/xylose mixtures to levulinic acid and furfural.
