Procedure

A solution of 2-benzoyl-6-nitrobenzoic acid (2.0 grams; 0.0074 mole) in 10 mls. of concentrated sulfuric acid (99.5% by weight) was stirred at 100° C for 3 hours, then cooled to room temperature and poured into a mixture of ice and water. The resulting mixture was filtered to recover the precipitated solids. The filter cake was then washed successively with a dilute aqueous solution of sodium carbonate and water, and dried to obtain 1-nitroanthraquinone (1.59 grams; 85% yield). The product was identified by comparison of its vapor phase chromatographic spectrum with that of an authentic sample.
