Procedure
The operation is as in Example 1 except for using 424 g of 1,4,4a,9a-tetrahydro-anthraquinone, 2 liters of toluene and 4 g of catalyst. After two hours of reaction, hydrogen is no longer absorbed. 28.5 Grams of 1,2,3,4-tetrahydro9,10-anthracene-diol containing the catalyst are repeated by filtration and, after concentration of the solution, 402 g of 1,2,3,4,4a,9a-hexahydro-9,10-anthracene-dione are obtained.
