Methanesulfonic acid (MsOH, MSA) or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH 3 SO 3 H and structure H 3 C−S(=O) 2 −OH. It is the simplest of the alkylsulfonic acids ( R−S(=O) 2 −OH ).
Ms 2 O may be prepared by the dehydration of methanesulfonic acid with phosphorus pentoxide. [2] P 2 O 5 + 6 CH 3 SO 3 H → 3 (CH 3 SO 2) 2 O + 2 H 3 PO 4. Ms 2 O can be purified by distillation under vacuum (distillation of a solid) or by recrystallization from Methyl tert-butyl ether/toluene.
Sulfonic acids are strong acids. They are commonly cited as being around a million times stronger than the corresponding carboxylic acid. For example, p-Toluenesulfonic acid and methanesulfonic acid have pK a values of −2.8 and −1.9, respectively, while those of benzoic acid and acetic acid are 4.20 and 4.76, respectively

Frederick Smith was spurred to create many of the chemical compounds, especially perchlorates and trace metal perchloric acid, in response to the needs of his colleagues in analytical chemistry. [17] This tradition is continued here and is the most commonly associated part of the business when a chemist or researcher hears of GFS Chemicals.

Methanedisulfonic acid is the organosulfur compound with the formula CH 2 (SO 3 H) 2. It is the disulfonic acid of methane. It is prepared by treatment of methanesulfonic acid with oleum. Its acid strength (pK a) is comparable to that of sulfuric acid. [3]
In the US, Honda does not offer any E85 powered flexfuel vehicles in 2009. [16] GM has stated a commitment to dedicate 50% of its production to Flex-Fuel E85 capable vehicles by the 2012 model year. [17] Also by 2012 all products of British luxury car-maker Bentley Motors will be Flex-Fuel using a patented fuel-system and an in-line fuel sensor.
