ABSTRACT:
Process for the removal of the residual sulfuric acid from the reaction mixture which has been obtained in the reaction of paraffin with sulfur dioxide, oxygen and water under irradiation by UV light and which has been freed from sulfur dioxide by degassing at an elevated temperature and from which the bulk of the sulfuric acid has been removed by concentration, by warming this concentrated product and adding as much of an alkali metal carbonate, peroxide, hydroxide, sulfate or sulfonate as is required to convert the residual sulfuric acid into an alkali metal bisulfate.
