Abstract

PURPOSE: To facilitate the extraction of the title compound useful as an assistant for the production of hydrofen peroxide, and to prepare the title compound economically, by adding a specific monohydric alcohol to a reaction mixture, thereby by improving the separability of an oil phase and a water phase of the reaction mixture.
CONSTITUTION: A 2-alkylanthraquinone is prepared by (1) cyclizing a compound I (R1 is 2W8C alkyl) in sulfuric acid or in oleum, (2) diluting the reaction mixture with water, and (3) extracting the objective compound with a hydrocarbon or a halogenated hydrocarbon in the presence of a monohydric alcohol of formula II (R2W4 are H, 1W16C alkyl, cycloalkyl, etc.; at least one of R2W4 is ≥3C alkyl, etc., or at least two of them are ethyl), e.g. butanol. The amount of the alcohol is 0.1W25wt%, pref. 0.3W10wt%, based on the sulfuric acid in the reaction mixture. The addition of the alcohol improves the separability of the oil phase and the water phase, and facilitates the extraction of the objective compound.
