Abstract

123,548. Hintikka, S. V. Jan. 17, 1918. p-Nitrotoluene-o-sulphonic acid is prepared by sulphonating p-cymene to its alpha-sulphonic acid and treating the sulphonation mixture at 40-60‹ C. with nitric acid and sulphuric acid (or at 60-70‹ C. with mixtures of nitrates and sulphuric acid), about 9 parts of nitric acid (specific gravity 1.48) being used for 10 parts of cymene; under these conditions, the isopropyl group is replaced by the nitro group.
