Abstract
Hydrochrysene is obtained by treating chrysene with hydrogen under pressure in the presence of dekalin as a dispersing agent and nickel on kieselguhr as a catalyst at temperatures between 220-300 DEG C. After completion of the reaction the catalyst is filtered off and the dekalin removed by distillation. After being crystallized from a mixture of alcohol and benzene a substance, probably consisting of octa- or dodeca-hydrochrysene, melting between 125-135 DEG C. was obtained.
