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.
MSA undergoes biodegradation by forming CO2 and sulphate.
Methanesulfonic acid is considered a green acid as Methanesulfonic acid is less toxic and corrosive in comparison to mineral acids.
The aqueous MSA solution has been considered a model electrolyte for electrochemical processes.
Applications of Methanesulfonic acid:
Methanesulfonic acid may be used:
Methanesulfonic acid is used as a catalyst to produce linear alkylbenzenes by the addition reaction between long-chain olefins and benzene.
Methanesulfonic acid is used to prepare polyaniline (PANI)/graphene composites with enhanced thermal and electrical properties.
Methanesulfonic acid is used as a catalyst for the transformation of glucose/xylose mixtures to levulinic acid and furfural.
Methane Sulfonic Acid finds application in Pharmaceutical & Agrochemical synthesis.

Methanesulfonic acid can be used as excellent eco-friendly cleaning agent in house hold and industrial cleaners.
Methanesulfonic acid also find application in Electroplating and Metal Surface Treatment.
Methanesulfonic acid is also an excellent Rust & Scale removing agent.
Methanesulfonic acid is used as an acid catalyst in organic reactions because Methanesulfonic acid is a non-volatile, strong acid that is soluble in organic solvents.
Methanesulfonic acid is convenient for industrial applications because Methanesulfonic acid is liquid at ambient temperature, while the closely related p-toluenesulfonic acid (PTSA) is solid.
However, in a laboratory setting, solid PTSA is more convenient.
Methanesulfonic acid can be used in the generation of borane (BH3).
By reacting methanesulfonic acid with NaBH4 in an aprotic solvent such as THF or DMS, the complex of BH3 and the solvent is formed.
Methanesulfonic acid is considered a particularly suitable supporting electrolyte for electrochemical applications, were stands as an environmentally friendly alternative to other acid electrolytes used in plating processes.
Methanesulfonic acid is also the electrolyte of choice in zinccerium (see cerium(III) methanesulfonate) and lead-acid (methanesulfonate)flow batteries.
Methanesulfonic acid (MsOH) or methanesulphonic acid (in British English) is a colorless liquid with the chemical formula CH3SO3H.
Methanesulfonic acid is the simplest of the alkylsulfonic acids.
Salts and esters of methanesulfonic acid are known as mesylates (or methanesulfonates, as in ethyl methanesulfonate).
Methanesulfonic acid is hygroscopic in its concentrated form.
Methanesulfonic acid may be considered an intermediate compound between sulfuric acid (H2SO4), and methylsulfonylmethane ((CH3)2SO2), effectively replacing an –OH group with a –CH3 group at each step.
This pattern can extend no further in either direction without breaking down the –SO2– group.
Methanesulfonic acid can dissolve a wide range of metal salts, many of them in significantly higher concentrations than in hydrochloric or sulfuric acid.
Methanesulfonic acid (MSA), the simplest alkanesulfonic acid, is a hygroscopic colorless liquid or white solid, depending on whether the ambient temperature is greater or less than 20 ºC.
Methanesulfonic acid is very soluble in water and oxygenated solvents, but sparingly soluble in most hydrocarbons.
In aqueous solution, Methanesulfonic acid is a strong acid (completely ionized).
MSA’s acidity and solubility properties make Methanesulfonic acid industrially valuable as a catalyst in organic reactions, particularly polymerization.
In many applications, Methanesulfonic acids advantage over concentrated sulfuric acid is that Methanesulfonic acid has similar acid strength but is not an oxidant.
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer.
The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper.
Three pathways can be found for the reaction of MSIA with ozone.
The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway.
By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, Methanesulfonic acid can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to Methanesulfonic acids oxidation by OH radical in the gas phase.
This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.

Methanesulfonic acid (MSA) was used as catalyst for the electrophilic addition of long-chain olefins such as 1-dodecene to benzene.
The influence of the temperature, the ratios of the reactants, the amount of MSA, and the stirring of the reaction mixture were investigated.
After a 3 h reaction time at 80 °C, a selectivity to the phenyldodecanes of more than 90% was obtained at 98% dodecene conversion.
MSA could be recycled at least five times after a treatment with water and dichloromethane and a subsequent water removal.
The presence of water in the reaction mixture was found to be detrimental for the activity of MSA.
The inhibitory products formed during the reaction, as well as the crude organic phase, have been proved also as responsible for MSA deactivation.
This method represents an environmentally benign alkylation route, because MSA could easily be separated from the reaction mixture via decantation and because Methanesulfonic acid could be reused.
In addition to that, MSA is biodegradable.

METHANE SULFONIC ACID
Methanesulfonic acid (CH3SO3H, MSA) is one of the major organosulfur acids formed from the photochemical oxidation of dimethyl sulfide (DMS) produced by oceanic phytoplankton.
MSA can react with metal halides (e.g. sodium chloride) in ambient aerosols to form methanesulfonate salts (e.g. sodium methanesulfonate, CH3SO3Na).
While the formation processes of MSA and Methanesulfonic acids salts are reasonably well understood, their subsequent chemical transformations in the atmosphere are not fully resolved.
MSA and Methanesulfonic acids salts accumulate near the aerosol surface due to their surface activities, which make them available to heterogeneous oxidation at the gas-aerosol interface by oxidants such as hydroxyl (OH) radicals.
In this work, the compositional changes of aerosol comprised of MSA and Methanesulfonic acids sodium salt (CH3SO3Na) are measured following heterogeneous OH oxidation.
An aerosol flow tube reactor is coupled with a soft atmospheric pressure ionization source (Direct Analysis in Real Time, DART) and a high-resolution mass spectrometer at a relative humidity (RH) of 90 %.
Aerosol mass spectra reveal that MSA and CH3SO3Na can be detected as methanesulfonate ion (CH3SO3⁻) with minimal fragmentation in the negative ionization mode.
Kinetic measurements show that OH oxidation with MSA and CH3SO3Na has an effective OH uptake coefficient of 0.45 ± 0.14 and 0.20 ± 0.06, respectively, revealing that MSA reacts with OH radical faster than Methanesulfonic acids sodium salt.
One possibility for the difference in reactivity of these two compounds is that CH3SO3Na is more hygroscopic than MSA.
The increase in the coverage of water molecules at the surface of CH3SO3Na might reduce the reactive collision probability between CH3SO3⁻ and OH radicals, resulting in a smaller reaction rate.
MSA and CH3SO3Na dissociate to form CH3SO3⁻, which tends to fragment into formaldehyde (HCHO) and a sulfite radical (SO3•−) upon oxidation.
Formaldehyde partitions back to the gas phase owing to Methanesulfonic acids high volatility, and SO3•− can initiate a series of chain reactions involving various inorganic sulfur radicals and ions in the aerosol phase.
Overall, the fragmentation and SO3•−-initiated chemistry are the major processes controlling the chemical evolution of MSA and Methanesulfonic acids sodium salt aerosols during heterogeneous OH oxidation.

Methane sulfonic acid is a strong organic acid used in numerous applications ranging from chemical and biofuel synthesis to industrial cleaning and metal surface treatment in the electronics industry.
The expansion is in line with the trend for top-performance and at the same time environmentally friendly technologies in various industries.
BASF’s proprietary process enables the production of MSA – a high-purity methane sulfonic acid.
Lutropur MSA is a sustainable alternative to other acids such as sulfuric, phosphoric or acetic acid.
As part of the natural sulfur cycle MSA is readily biodegradable.
Further benefits in practical applications come, for example, from Methanesulfonic acids nonoxidizing nature, the high solubility of Methanesulfonic acids salts and the absence of color and odor.
Methanesulfonic acid/SiO2 (1 mL/0.3 g) was found to be as an expeditious mixture in the synthesis of 2-substituted aromatic and aliphatic benzothiazoles at 140 °C using carboxylic acids.
After a simple workup, benzothiazoles were obtained in good yields.
Simplicity, use of widely available and diverse carboxylic acids, and easy handling of the reaction conditions are among the benefits of the method.

Concentrations of aerosol methanesulfonic acid (MSA) and non-sea-salt (nss) sulfate were measured at six island stations in the Pacific Ocean to investigate regional and seasonal patterns of organosulfur emissions and the origin of nss sulfate over the Pacific.
The mean MSA concentrations, in μg/m3, at the stations were: Shemya, 0.097±0.098; Midway, 0.029±0.021; Fanning, 0.044±0.012; American Samoa, 0.026±0.012; New Caledonia, 0.021±0.009; Norfolk, 0.024±0.019.
The extremely high MSA levels found at Shemya indicate a major source of organosulfur emissions in the western North Pacific.
Significant seasonal trends in MSA were observed, with higher MSA occurring during warm months.
The amplitude of the seasonal variation was greatest at higher latitude stations.
At Fanning and American Samoa, which have minimal input of continental material, there is a significant positive correlation between MSA and nss sulfate.
MSA/nss sulfate ratios at other Pacific stations exhibit greater variability, which may be related to variations in: the input of continentally derived sulfate, the composition of oceanic organosulfur emissions, and atmospheric reaction pathways.

MSA
Methanesulfonic acid (MSA, 70 wt %) is widely used in electrochemical systems and is an excellent catalyst for the esterification, alkylation, and condensation of organic compounds.
Lower reaction temperatures are required when using MSA rather than titanate catalysts, and purer, more colorless products can be obtained using MSA than those produced using sulfuric or para-toluenesulfonic acid as the catalyst.
Anhydrous MSA is also particularly well suited for pharmaceutical applications and as a catalyst for aromatic alkylation.
The current commercial process for the synthesis of MSA involves chlorine oxidation of methylmercaptan.
While this process is highly productive, Methanesulfonic acid produces six moles of HCl per mole of MSA, resulting in a coupling of the demand for the primary product and the byproduct.
As an alternative Methanesulfonic acid is interesting to consider a direct methane sulfonation route using SO3 or SO2 and O2 as the sulfonating agent.
Sen and co-workers and, more recently, we have shown that a compound such as K2S2O8 can be used as a free radical initiator to sulfonate methane with SO3 in fuming sulfuric acid.

Since methanesulfonic acid (MSA), does not cause sulfonation of aromatic rings, Methanesulfonic acid was used at elevated temperatures to prepare 1-indanones and 1-tetralones through cyclization of 3-arylpropanoic and 4-arylbutanoic acids.
The twelve ketones which were prepared from MSA-catalyzed cyclization of 3 and 4-aryl substituted carboxylic acids are pesented in a table, along with their yields, time and temperature.
Studies under a variety of temperatures, concentrations and reaction times show that 30 min. to 3 hours is needed for cyclization depending on the reactivity of the starting material.
The use of neat MSA as a substitute for Friedel-Crafts catalyst was not promising.
Trial studies in which m-xylene was treated with acetic acid in the presence of anhydrous MSA at 110/sup 0/C for 3 hours gave low yields of acetylation product (ca. 30%), and gas chromatography analysis of the product showed unreacted m-xylene.
