実験手順

1265 parts by weight of 2-nitroanthraquinone are reacted at 270° C. with elemental bromine in the presence of 60 parts by weight of nitrobenzene in a laboratory apparatus as described in Example 1. When the reaction is complete, the melt is discharged into 2,000 parts by weight of vigorously stirred methanol at 200° C. The suspension so obtained is refluxed for 1 hour, cooled to 50° C., filtered and dried, affording 1390 g of 2-bromoanthraquinone (97% yield) in 98% purity.
