Summary Hydrogenation of 2-naphthol over copperchromite catalyst yields at least 77% of pure 1, 2,-3, 4-tetrahydro-2-naphthol, 7-8% of 5, 6, 7, 8-tetrahydro-2-naphthol and about 13% of slightly impure 1, 2, 3, 4-tetrahydr0-2-naphthol from which more pure material may be isolated. Simple separation of the mixture was accomplished by conversion of the phenol constituent to its non-volatile sodium salt and distillation of the alcoholic constituent from ...
