Product Introduction:

Methanesulfonic acid is a caustic chemical, or MSA for short. Generally colorless or slightly brown oily liquid, solid at low temperature. The molecular formula is CH4O3S, the structural formula is CH3SO3H, and the molecular weight is 96.11. It is soluble in water, alcohol and ether, insoluble in alkane, benzene, toluene, etc. It does not decompose in boiling water and hot lye, and has a strong corrosive effect on metal iron, copper and lead.

Methanesulfonic acid has a strong stimulating effect on skin and mucous membranes, but it is less toxic than methanesulfonic acid. Its products have broad application prospects in the field of electroplating and have been proven to be good substitutes for fluoroboric acid or phenolsulfonic acid.

Methanesulfonic acid is an environmentally friendly and new type of tin plating system, which has the advantages of strong acidity, small molecular weight, low corrosiveness, high catalytic activity and low toxicity. As an electrolyte for electrochemical processes, it is superior to fluoroboric acid and fluorosilicic acid in terms of function and environmental protection, and is a good substitute for fluoroboric acid and fluorosilicic acid.

The earliest research on the use of methanesulfonic acid in electroplating was in 1940, but it was not until the early 1980s that developed countries developed organic sulfonate systems to replace fluoroborate electroplating SnPb alloy baths, mainly alkyl sulfonates. A new process for electroplating SnPb alloys.

In recent years, the methanesulfonic acid electroplating system has attracted more and more attention, and the application of the methanesulfonate plating solution has been increasing, and it is gradually replacing the fluoroboric acid system with high toxicity and complicated wastewater treatment. At present, methanesulfonic acid has been applied to tin and tin-lead alloy electroplating, and gradually developed into copper-lead-tin alloy coating, immersion tin coating, silver plating and other fields.

Product Usage:

Methanesulfonic acid is used as a solvent and catalyst in electroplating and electrochemical processes, alkylation, esterification and condensation reactions, lead recovery, chemical intermediates for the manufacture of pharmaceuticals and pesticides, petroleum refining and lubricant additives, extraction and process solvents, etc. and plastic stabilizers.

Methanesulfonic acid is an excellent catalyst for esterification, condensation reaction, alkylation, olefin polymerization and curing of conversion film.

At present, methanesulfonic acid with a concentration of 70% is used in the field of electrochemistry, and methanesulfonic acid with a concentration of 99% is used in pharmaceuticals, pesticides and chemical raw materials.

Application of 70% methanesulfonic acid:

70% methanesulfonic acid is mainly used in electroplating field, resin catalyst, electronic cleaning agent. This concentration of methanesulfonate electroplating solution is widely used in tin and tin-lead alloy electroplating. The bright pure tin electroplating of methanesulfonic acid type has fine and uniform coating crystals, bright silvery white, and has good solderability. Suitable for high-end electronics industry.

The plating solution has high electroplating speed, wide current density range, fast deposition speed, excellent deep plating ability, can maintain good welding performance after standard aging test or long-term storage, does not contain fluoroboric acid , Wastewater treatment is easy, low corrosiveness, is conducive to environmental protection.

99% methanesulfonic acid is mainly used for the production of antibiotic intermediates.

Methane sulfonate electroplating option has actually been put on tin as well as tin-lead alloy electroplating. The item functions are as adheres to:

  1. Methanesulfonic acid kind brilliant pure tin electroplating, the finish crystal is fine, uniform, intense silver-white, with excellent solderability, ideal for the electronics sector.
  2. The electroplating solution has high electroplating speed, wide current density range, fast deposition speed and excellent deep plating ability.
  3. After conventional aging examination or lasting storage space, it can still preserve great welding efficiency.
  4. Does not contain fluoroboric acid, easy to treat wastewater, low corrosiveness, and conducive to environmental protection.
