Versuchsvorschrift

25.4 g (0.1 mole) of para-toluic anhydride was dissolved in 100 ml of warm nitromethane and then 9.6 g (0.1 mole) of methane sulfonic acid was added. The reaction mixture was stirred for 20 minutes and then filtered, giving 13.72 g (0.1 mole) of para-toluic acid precipitant. The reaction was quantitative, resulting in the para-toluic methane sulfonic anhydride dissolved in nitromethane.
