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.
一种制备1,2,3,4-四氢-9,10-蒽二醇的过程,其中在液相中对1,4,4a,9a-四氢蒽醌进行催化氢化,得到1,2,3,4,4a,9a-六氢-9,10-蒽二酮,然后在酸的存在下对后者进行异构化,得到1,2,3,4-四氢-9,10-蒽二醇。
