Ojiji
Acid Methanesulfonic bụ alkyl sulfonic acid kachasị mfe. Mmiri mmiri na-enweghị agba. Ọ dị mfe ịgbaze na mmiri, ọ na-agbaze ntakịrị na ihe ndị na-agbaze organic. Acid siri ike na pKa nke -0.6. A naghị etinye ya na mmiri ọkụ ma ọ bụ ngwọta alkaline ọkụ. Enwere ike ịmepụta methanesulfonic acid site na oxidation nke methyl mercaptan ma ọ bụ dimethyl disulfide na oxygen ma ọ bụ nitric acid. Enwere ike ịkwadebe ya site na ngwọta sodium sulfite na dimethyl sulfate na mmiri na 100 ° C.
