Abstract
109,709. Dennis, L. M. Dec. 7, 1916. Sulphuric acid.-Sulphonic acids of aromatic hydrocarbons are separated from the excess of sulphuric acid contained in the product of sulphonation by treating the mass with an organic solvent which dissolves the sulphonic acid but not the sulphuric acid, and separating the layer of sulphonic acid solution from the sulphuric acid. The sulphuric acid may be drawn off and used for any desired purpose. Suitable organic solvents are benzene for benzene-monosulphonic acid and toluene for benzene disulphonic acids or naphthalene sulphonic acids.
