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.
1-硝基蒽醌是通过以下步骤制备高纯度的:部分氧化3-硝基-o-二甲苯(I)以制备2-甲基-3-硝基苯甲酸(II),将II转化为2-甲基-3-硝基苯甲酰卤(III),将III转化为新的中间体2-甲基-3-硝基苯并酮(IV),将IV氧化为2-苯甲酰基-6-硝基苯甲酸(V),并将V环化为1-硝基蒽醌。
