Procedure

Acenaphthene was hydrogenated by the same procedure as in Example 1 except that the catalyst was replaced by a 5% Pd/C catalyst and reaction was effected at 160° C. for 6 hours. No substantial change was observed in the distribution of reaction products at the end of 4 hour reaction. Perhydroacenaphthene was finally obtained in a yield of 99.6%. The yields of Nos. 1 to 4 isomers were 33.5%, 11.8%, 24.5%, and 29.7%, respectively.
