실험 절차

A process for the preparation of 1,2,3,4-tetrahydro-9,10-anthracene-diol, in which catalytic hydrogenation of 1,4,4a,9a-tetrahydro-anthraquinone is carried out in the liquid phase to give 1,2,3,4,4a,9a-hexahydro-9,10-anthracene-dione followed by isomerization of the latter in the presence of an acid to give 1,2,3,4-tetrahydro-9,10-anthracene-diol.
