Abstract
Sulfuric acid is substantially completely removed from mixtures in which it occurs together with sulfonic acids by extraction with concentrated hydrochloric acid. The extraction can be carried out counter-current wise with from 50 to 150 volume percent of hydrochloric acid, depending on the number of stages used. This process is particularly useful for removing sulfuric acid from the heavy product phase resulting from the sulfoxidation of paraffins.
