ABSTRACT:
Alkanedisulfonic acids, particularly methanedisulfonic acid (methionic acid), can be prepared by reacting the corresponding alkanesulfonic acid with chlorosulfonic acid. The reaction is carried out by heating the reactants with agitation, preferably under substantially anhydrous conditions in the presence of oxygen and at substantially atmospheric pressure. Particularly good yields are obtained using an activated carbon co-catalyst.
