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.[1] 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[2] The aqueous MSA solution has been considered a model electrolyte for electrochemical processes.[3]
Application
Methanesulfonic acid may be used:
- As a catalyst to produce linear alkylbenzenes by the addition reaction between long-chain olefins and benzene.[4]
- To prepare polyaniline (PANI)/graphene composites with enhanced thermal and electrical properties.[5]
- As a catalyst for the transformation of glucose/xylose mixtures to levulinic acid and furfural.[6]
