Reaction Steps

A process for the preparation of 1-nitroanthraquinone by (1) reacting 5-nitro-1,4-naphthoquinone with butadiene, (2) oxidising the 1-nitro-5,8,11,12-tetrahydroanthraquinone so obtained to 1-nitroanthraquinone, and (3) isolating the 1-nitroanthraquinone, which process comprises reacting in step (2) 1-nitro-5,8,11,12-tetrahydroanthraquinone (a) with oxygen, as inorganic peroxide compound or a metal oxide as oxidising agent and isolating 1-nitro-5,8-dihydroanthraquinone, and then (b) oxidising this intermediate to 1-nitroanthraquinone with one of the above oxidising agents.
