ABSTRACT:
An environmentally acceptable process is provided to synthesize a 2-(alkylbenzoyl)benzoic acid suitable for synthesizing a 2-alkylanthraquinone without further purification. Usually the crude product is isolated from the reaction mixture by a succession of steps which generate a large volume of aqueous waste. The present process eliminates or decreases these wastes and produces a product of sufficient purity for synthesizing as 2-alkylanthraquinone.
