Methane Sulfonic Acid (MSA) CH3SO3H

Methane Sulfonic Acid 70% in Electrochemical Applications:

  • Replacement for fluoboric acid and fluoborates in tin/lead plating
  • Wire and steel strip tin plating
  • Metal finishing of silver, copper, nickel and palladium
  • Immersion and spray stripping
  • Lead recovery from scrap batteries
  • Electrolytic stripping
  • Electropolishing
  • Regenerating ion exchange resins

    Methane Sulfonic Acid 70% is an excellent catalyst for esterification, alkylation and condensation reactions. Methane Sulfonic Acid yields purer and lower color esters than both sulfuric and para-toluene sulfonic acids. Unlike titanate catalysts, Methane Sulfonic Acid can be used at low temperatures.

    Key Benefits of Methane Sulfonic Acid in Esterifcation:

  • Low molecular weight
  • Pure and non-oxidizing
  • Limited by-products
  • High thermal stability
  • A clear rag layer
  • Recyclable
  • Biodegradable
  • Easily handled
  • Less corrosive than H2SO4

    Methane Sulfonic Acid is the catalyst of choice for: acetates, acrylates, phthalates, fatty acid esters and thioglycolates.

    Anhydrous Methane Sulfonic Acid

    Anhydrous Methane Sulfonic Acid is particularly well suited for pharmaceutical applications and as a catalyst for aromatic alkylation. For more information please visit the AMSA product page.
