ABSTRACT:
A process for removing sulfuric acid from the reaction mixture obtained in the sulfoxidation of paraffins, which comprises adding an organic amine sulfate to the reaction mixture and removing the phase consisting of water and sulfuric acid which thereby separates out, adding to the remaining phase containing alkanesulfonic acid and alkanesulfonic acid amine salt an amount of an alkali metal hydroxide sufficient to convert the alkanesulfonic acid and the alkanesulfonic acid amine salt into the alkali metal alkanesulfonate, the organic amine being liberated, removing the paraffin from this mixture, together with the free organic amine, by steam distillation, removing the free organic amine from the paraffin by extraction with sulfuric acid and employing the resulting organic amine sulfate again at the start of the whole process for removing the sulfuric acid.
