ABSTRACT:
1-Nitroanthraquinone is produced in highly pure form by a process comprising the steps of: partially oxidizing 3-nitro-o-xylene (I) to 2-methyl-3-nitrobenzoic acid (II) converting II to 2-methyl-3-nitrobenzoyl halide (III), converting III to the novel intermediate 2-methyl-3-nitrobenzophenone (IV), oxidizing IV to 2-benzoyl-6-nitrobenzoic acid (V) and cyclizing V to 1-nitroanthraquinone.
