Preparation of Anthraquinone from Anthracene with Catalyst of Mixed Light Rare-Earth Ore Nitrates

A preparation method of anthraquinone with industrial significance through the direct oxidation in liguid phase from anthracene as raw material, has been realized in this laboratory. The new catalyst is the mixed light rare-earth ore nitrates, which is very cheaper and is very plentiful in this country. The yield in single-pass operation is 77.1%. The catalyst is effective in multiple circular processes.
