ABSTRACT:
Process for the concurrent synthesis of benzophenone, anthraquinone, and o-dibenzoylbenzene by pyrolysis of benzoic acid salts of yttrium, erbium, and dysprosium and mixtures thereof at temperatures of from about 200.degree. C. to 500.degree. C. and a pressure of about 0.1 to about 100 atmospheres. In an alternative method, a benzoic acid compound is passed through an oxide of yttrium, erbium, dysprosium and mixtures thereof in the presence of steam.
