Methanesulfonic acidEnvironmental chamberParticulate sulfuric acid and methanesulfonic acid (MSA) are known to form through oxidation of reduced sulfur compounds, however, the mechanisms by which these compounds form are not well understood. Additionally, the aerosol yields and ratio of MSA to sulfuric ...
variants or methane sulfonic acid chemistry : a corrosive liquid acid CH4O3S that is used especially as a catalyst in chemical reactions (such as polymerization and esterification) Methanesulfonic acid has been developed as an esterification catalyst in place of sulfuric acid for the synthesis of...
Sulfuric acid (H2SO4) is by far the most often used acid in hydrometallurgy. It is widely applied for leaching metals from ores, concentrates, industrial process residues and other metal-containing streams, and it is the acid of choice in electrolytes for the electrowinning and electrorefining o...

Sulfur trioxide is more reactive than sulfuric acid or its derivatives and is often used for aromatic sulfonation, particularly when modified as its adducts with dioxane or pyridine. The addition of sulfur trioxide across a carbon–carbon double bond to give an aliphatic sulfonic acid is possible,...
The electrochemical oxidations of Ce3+to Ce4+on Pt rotating disk electrode(RDE) in both sulfuric acid and methanesulfonic acid(MSA) solutions were studied by using cyclic voltammetry and linear sweep voltammetry.The complexing behaviors of Ce3+/Ce4+were preliminarily probed and the exchange current ...

In the presence of H2O2 as a radical initiator, the reaction of SO2 and O2 in trifluoroacetic acid (TFAOH) furnished trifluoroacetylsulfuric acid (TFAOSO3H), which served as the radical propagator to facilitate H-abstraction of methane at low temperatures. In typical reactions, sulfur dioxide ...

However, quantitative concentrations and thermodynamic properties of MSA and sulfuric acid (SA; H2SO4) in the presence of water (W; H2O) remain largely uncertain. In this study, flow tube reactor was used to investigate the effects of each reactant on new particle formation (NPF) in a ...
