Reaction Steps

The octahydro-anthraquinone (OHAQ) reaction is initially a highly exothermic and is immediately followed by the rapid elimination of hydrogen which has a pronounced cooling effect on the reaction system. Reaction times of less than 1 minute past the exotherm with a rhodium on carbon catalyst provided yields of 62 percent anthraquinone, along with isomerized OHAQ and isomerized THAQ. If the same reaction is conducted with palladium on a carbon support, a 75 percent yield of anthraquinone is obtained along with the isomerized OHAQ and isomerized THAQ. The reaction can be visualized to be the following: ##STR6##
