Lead methanesulfonate solution is recognized for Lead methanesulfonates chemical characteristics and comes as a colorless, slightly yellowish aqueous solution.
Lead methanesulfonate is a colorless liquid that is stable under normal conditions of use and storage.
Lead (II) methanesulfonate is corrosive to metals.
The concentration is 860 g/l minimum ( 450g of lead per liter).
Methanesulfonic Acid is proving to be an exceptional cleaning alternative for the food industry, providing effectiveness, productivity, dependability, and economy.
MSA is also used in fine chemical synthesis as solvent (rearrangement and condensation reactions), catalyst or to produce mesylates (amines salification).
Methanesulfonic Acid contains no phosphorous or nitrogen and contributes very Iittle COD (chemical oxygen demand) to effluent entering a water treatment plant.
Methanesulfonic Acid is 100 percent biodegradable, as determined by OECD Standard 301F.

Uses
Lead (II) methanesulfonate is used in surface treatment for tin/lead alloys and lead coating without fluoborate.
Lead (II) methanesulfonate is particularly suitable for Printed Circuit Boards plating and real to real process.
Lead Methly Sulfonate is also used as a catalyst and reagent.
Lead methanesulfonate is used in plating processes (both electrolytic and electroless) for electronic components, such as printed circuit boards.
A low alpha particle-emitting lead methanesulfonate is used in sensitive semiconductor tin-lead plating.
Electroplating is a process for applying a metallic coating on a metal surface by electrodeposition from a suitable electrolyte solution for imparting corrosion resistance and direct production of printed circui boards without etching out of a piece of copper sheet.
Lead Methly Sulfonate is also used for batteries in special applications.
Lead methanesulfonate is used as reagent, catalyst and precursor.
Other applications for LEAD METHYL SULFONATE are: thin film deposition, industrial chemistry, pharmaceuticals, LED manufacturing, and others.
Lead Methly Sulfonate is a compound used in the preparation of PbO2-coated electrodes.
Electroplating is a process for applying a metallic coating on a metal surface by electrodeposition from a suitable electrolyte solution for imparting corrosion resistance and direct production of printed circuit boards without etching out of a piece of copper sheet.
The object to be plated is connected as the cathode in the electrolyte solution and then passing electric current is passed through the anode which causes the ions to be deposited to the material.
Lead Methly Sulfonate is used as the acid electrolyte in the electroplating because many metals which are not soluble in mineral or organic acids are soluble, particularly tin and lead plating.
Stannic sludge formation is rare as methanesulfonic acid is a non-oxidizing acid.
For electric plating and other electronic industry.
Modeling of Lead-acid Flow Battery
Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ).
A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries.
Soluble lead-acid flow battery (SLFB) is a new kind of lead-acid flow battery in which products of discharge remain in dissolved state.
SLFB contains mixture of lead (II)-methanesulfonate as the electroactive material dissolved in methanesulfonic acid.
During charging, P bO2 and P b are formed at anode and cathode respectively.
During discharge, lead (II)-methanesulfonate is regenerated at both electrodes.
The flow battery thus has potentials to overcome a number of drawbacks of the conventional lead-acid batteries, associated with solid discharge products.
In experimental studies elsewhere, it has been observed that the voltage-time curve for charge-discharge cycles of SLFB at constant current follows a specific pattern, which impacts the efficiency and capacity of the battery.
A simple mathematical model based on diffusive and convective transport of ionic species in the system and their reaction on the electrode surfaces is developed in the present work.
The model is used to predict the charge-discharge characteristics of SLFB along with energy efficiency and charge efficiency during the cycling.
The model can also be used to predict the cycle life of a SLFB.
Electrochemistry module with moving interface available in COMSOL Multiphysics has been used to solve the model.
