Versuchsvorschrift
16.6 g (0.10 mol) of 2-tert-butylhydroquinone was placed in a 200 cc 3-neck flask. After adding 17.4 g (0.20 mol) of powdery manganese dioxide, 100 cc of toluene was added thereto, and the mixture was heated with stirring. The temperature was maintained at 70° C. for 3 hours. After cooling to room temperature, the manganese dioxide was removed by filtration by means of suction using Celite as a filter aid. Then the manganese dioxide was washed with 50 cc of toluene, and the toluene was evaporated to dryness, by which 2-tert-butyl-1,4-benzoquinone was obtained. The yield was 80% and the melting point was 48°-50° C.
