Methanesulfonic acid Chemical Properties,Uses,Production
Chemical Properties
Methanesulfonic acid is a colourless or light yellow liquid having a melting point of 20° C, is a strong acid acting corroding but not oxidizing.
Methanesulfonic acid is used in the electroplating industry and for organic syntheses, in particular as a catalyst for alkylations, esterifications, and polymerizations. Beyond that, methanesulfonic acid is used as a starting material for the preparation of methanesulfonyl chloride.
Uses
Polymerization catalyst.
Methanesulfonic acid has been developed as an esterification catalyst in place of sulfuric acid for the synthesis of resins in paints and coatings. One of the major advantages of methanesulfonic acid over sulfuric acid is that it is not an oxidizing species.
Preparation
Methanesulfonic acid is produced predominantly by oxidizing methylthiol or dimethyl disulfide using nitric acid, hydrogen peroxide, chlorine or by employing electrochemical processes.
Definition
ChEBI: An alkanesulfonic acid in which the alkyl group directly linked to the sulfo functionality is methyl.
General Description
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. It is considered a green acid as it is less toxic and corrosive in comparison to mineral acids.1 The aqueous MSA solution has been considered a model electrolyte for electrochemical processes.
Hazard
Toxic by ingestion, skin irritant, corrosiveto tissue.
Safety Profile
Poison by ingestion and intraperitoneal routes. May be corrosive to skin, eyes, and mucous membranes. Explosive reaction with ethyl vinyl ether. Incompatible with hydrogen fluoride. When heated to decomposition it emits toxic fumes of SOx. See also SULFONATES.
Purification Methods
Dry the acid, either by azeotropic removal of water with *benzene or toluene, or by stirring 20g of P2O5 with 500mL of the acid at 100o for 0.5hours. Then distil it under vacuum and fractionally crystallise it by partial freezing. Sulfuric acid, if present, can be removed by prior addition of Ba(OH)2 to a dilute solution, filtering off the BaSO4 and concentrating under reduced pressure; and is sufficiently pure for most applications.
