摘要:
A process for preparing alkanesulfonic acids from dialkyl sulfites comprises the following steps: rearrangement of dialkyl sulfite in the presence of a suitable catalyst to form the corresponding alkyl alkanesulfonate and hydrolysis of the resulting alkyl alkanesulfonate to give the corresponding alkanesulfonic acid.
