Abstract

PURPOSE: To prepare the title compound useful as industrial chemicals such as pesticides, easily, in high purity and high rate of reaction, by the isomerization of 1,4,4a,9a-tetrahydroanthraquinone in an inert solvent in the presence of an aromatic sulfonic acid.
CONSTITUTION: The compound IV (1,4-dihydro-9,10-dihydroxyanthraquinone) is prepared by the isomerization of the compound III (1,4,4a,9a-tetrahydroanthraquinone) in the presence of 0.02W1 wt.% of an aromatic sulfonic acid, at 50W 150°C. The compound III is prepared by the Diels-Alder reaction of the compound I (1,4-naphthoquinone) with the compound II (butadiene) in an inert solvent (pref. aromatic hydrocarbons such as benzene, alkylbenzene, etc.). The compound I is pref. obtained by the successive and selective extraction of gas obtained by the catalytic gas phase oxidation of naphthalene, first with an aqueous solvent and then with an aromatic hydrocarbon.
USE: Accelerator for the digestion of pulp; antioxidant of rubber, raw material of anthrone, etc.
