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.
