The process for separating sulfuric acid from the sulfoxidation output obtained when paraffins are reacted with sulfuric acid, oxygen and water in the presence of ultraviolet light, using an alcohol containing at least 5 C atoms, is improved by treating the sulfoxidation output with a 0.25 to 2.5 fold amount by weight of a mixture of n (a) 40 to 95% by weight of alcohol, and n (b) 5 to 60% by weight of paraffins and the aqueous phase formed thereby is separated with the sulfuric acid. |
