HISTORY AND SYNTHESIS of LUTROPUR MSA METHANESULFONIC ACID 70%:
Early history
German chemist Hermann Kolbe discovered Lutropur MSA Methanesulfonic acid 70% between 1842 and 1845 and originally termed it methyl hyposulphuric acid.
The discovery stemmed from earlier work by Berzelius and Marcet in 1813, who treated carbon disulfide with moist chlorine and produced a compound they named "sulphite of chloride of carbon".

By reacting Lutropur MSA Methanesulfonic acid 70% with barium hydroxide Kolbe demonstrated it to actually be trichloromethylsulfonyl chloride (CCl₃SO₂Cl in modern notation).
2 CCl3SO2Cl + 3 Ba(OH)2 → Ba(CCl3SO3)2 + 3 BaCl2 + 2 H2O

From resulting barium trichloromethylsulfonate Kolbe isolated the free acid, which he was then able to sequentially dechlorinate by electrolytically generated atomic hydrogen to ultimately yield Lutropur MSA Methanesulfonic acid 70%.
CCl3SO3H + 3 H → CHCl2SO3H + 2 H + HCl → … → CH3SO3H + 3 HCl

Kolbe's research on methanesulfonic and chloroacetic acids was hailed by Berzelius as strong evidence for his theory of copulated compounds, a modification of radical theory to accommodate substitution reactions which posited the combination of organic and inorganic moieties without significantly altering the properties of the latter.

Later in the 19th century, the name transitioned to methyl sulphonic acid.
Other historical laboratory synthesis routes included oxidizing methanethiol, dimethyl disulfide or methyl thiocyanate with nitric acid.

INDUSTRIAL PRODUCTION of LUTROPUR MSA METHANESULFONIC ACID 70%:
The first commercial production of Lutropur MSA Methanesulfonic acid 70%, developed in the 1940s by Standard Oil of Indiana, was based on oxidation of dimethylsulfide by O2 from air.
Although inexpensive, this process suffered from a poor product quality and explosion hazards.

Starting from the 1960s, it received a shortened name of mesylic acid after the term for the "mesyl" group coined by Helferich et al. in 1938.
In 1967, the Pennwalt Corporation (USA) developed a different process for dimethylsulfide (as a water-based emulsion) oxidation using chlorine, followed by extraction-purification.

In 2022 this chlorine-oxidation process was used only by Arkema (France) for making high-purity Lutropur MSA Methanesulfonic acid 70%.
This process is not popular on a large scale, because it co-produces large quantities of hydrochloric acid.

Between years 1970 and 2000 Lutropur MSA Methanesulfonic acid 70% was used only on a relatively small-scale in niche markets (for example, in the microelectronic and electroplating industries since the 1980s), which was mainly due to its rather high price and limited availability.

However, this situation changed around 2003, when BASF launched commercial production of Lutropur MSA Methanesulfonic acid 70% in Ludwigshafen based on a modified version of the aforementioned air oxidation process, oxidising dimethyldisulfide with nitric acid which is then restored using atmospheric oxygen.

The former is produced in one step from methanol from syngas, hydrogen and sulfur.
An even better (lower-cost and environmentally friendlier) process of making Lutropur MSA Methanesulfonic acid 70% was developed in 2016 by Grillo-Werke AG (Germany).

Lutropur MSA Methanesulfonic acid 70% is based on a direct reaction between methane and oleum at around 50 °C and 100 bar in the presence of a potassium persulfate initiator.
Further addition of sulfur trioxide gives Lutropur MSA Methanesulfonic acid 70% instead.
This technology was acquired and commercialized by BASF in 2019.

PRODUCTION of LUTROPUR MSA METHANESULFONIC ACID 70%:
HISTORICAL METHODS
Lutropur MSA Methanesulfonic acid 70% was first discovered by German chemist Hermann Kolbe between 1842 and 1845 during his pioneering work in organic synthesis, where he initially named it "methyl hyposulphuric acid" to reflect its structural analogy to inorganic sulfuric acid derivatives.
This discovery emerged from Kolbe's efforts to demonstrate that organic compounds could be synthesized from inorganic precursors, challenging prevailing vitalist theories in chemistry.

In the ensuing decades of the 19th century, Lutropur MSA Methanesulfonic acid 70% was prepared in laboratory settings as part of broader investigations into organic sulfur chemistry.
Early synthetic routes involved the oxidation of methanethiol (CH3SHCH3SH) or dimethyl disulfide ((CH3)2S2(CH3)2S2) using nitric acid as the oxidant, yielding the acid through sequential sulfur oxidation steps.

These methods, while foundational, were constrained by low yields and the inherent hazards of handling concentrated nitric acid, which posed risks of explosive reactions and toxic fumes in uncontrolled lab environments.
By the 1940s, advancements shifted toward milder conditions when researchers at Standard Oil Company of Indiana developed a process for oxidizing dimethyl sulfide ((CH3)2S(CH3)2S) with air or molecular oxygen (O2O2), often catalyzed to enhance selectivity.

This approach, detailed in early industrial patents and reports, improved efficiency over prior nitric acid methods and represented a transitional step toward commercial scalability in sulfur acid synthesis, enabling the first industrial production of Lutropur MSA Methanesulfonic acid 70%.
Overall, these historical preparations underscored the compound's role in 19th-century sulfur chemistry research, predating broader industrial adoption.

INDUSTRIAL PROCESSES of LUTROPUR MSA METHANESULFONIC ACID 70%:
The primary industrial production of Lutropur MSA Methanesulfonic acid 70% began in the mid-20th century with processes focused on efficient, large-scale synthesis using sulfur-containing feedstocks.
One of the earliest commercial methods, developed by the Pennwalt Corporation in 1967 and now operated by Arkema SA, involves the two-step chlorine oxidation of an aqueous emulsion of dimethyl sulfide.
In the first step, dimethyl sulfide reacts with chlorine to form methanesulfinyl chloride and methyl chloride:

(CH3)2S+Cl2→CH3S(O)Cl+CH3Cl
This intermediate is then hydrolyzed with water to yield MSA and hydrogen chloride:
CH3S(O)Cl+H2O→ CH3SO3H+HCl

The process operates under ambient conditions with high conversion yields but generates HCl as a byproduct, requiring careful handling, and results in MSA with potential chloride impurities that necessitate purification for certain applications.

In 2003, BASF SE introduced a modified, chlorine-free process at its Ludwigshafen facility, emphasizing higher yields and environmental benefits through the air oxidation of dimethyl disulfide (DMDS), a byproduct often sourced from petrochemical or pulp industries.
DMDS is first derived from methanol and hydrogen sulfide via methanethiol:

CH3OH+H2S→CH3SH+H2O
2CH₃SH + S → CH₃SSCH₃ + H₂S
Subsequent catalytic air oxidation of the resulting methanethiol intermediate produces MSA with minimal waste:

2CH₃SH + 3O₂ → 2CH₃SO₃H
This method achieves yields exceeding 95% and utilizes inexpensive feedstocks, reducing overall production costs while avoiding chlorinated byproducts.

A more recent innovation, patented by Grillo-Werke AG in 2016 and commercialized by BASF in 2019, employs direct sulfonation of methane with sulfur trioxide in oleum under moderate conditions (approximately 50°C and 100 bar), initiated by an electrophilic agent such as di(methanesulfonyl) peroxide.
The core reaction is:
CH₄ + SO₃ → CH₃SO₃H

This achieves near-100% atom economy with no side products or metal catalysts, leveraging abundant, low-cost methane as feedstock and minimizing waste compared to earlier routes.
Pilot-scale production reached up to 20 tons per year, paving the way for broader industrial adoption.
These processes offer key advantages, including reduced environmental impact through lower waste generation and utilization of inexpensive or recycled feedstocks like methane and DMDS byproducts from other sectors.

Major producers include BASF SE (with a capacity of about 50,000 metric tons annually), Arkema SA, and Grillo-Werke AG, contributing to a global production volume of several tens of thousands of tons per year.
