Abstract

There is provided a process for producing adamantanol and adamantanone which comprises reacting adamantane and oxygen in the presence of an oxidation catalyst constituted of a rare earth metal salt and a promoter containing an element selected from group 4 to group 10 of the new Periodic Table, and it is made possible through the production process according to the present invention to produce 2-adamantanol and 2-adamantanone in a high selectivity, high efficiency and safety by oxidizing adamantane under a mild reaction condition.

Claims (4)

1. A process for producing adamantanol and adamantanone which comprises reacting adamantane and oxygen in the presence of an oxidation catalyst constituted of a rare earth metal salt and a promoter containing an element selected from group 4 to group 10 of the new Periodic Table.

2. The process for producing adamantanol and adamantanone according to claim 1 , wherein the rare earth metal is europium, ytterbium or samarium which are each trivalent.

3. The process for producing adamantanol and adamantanone according to claim 1 , wherein the promoter in the catalyst system comprises a compound of a metal selected from among titanium, cobalt, vanadium, chromium and manganese each belonging to any of group 4 to group 7 of the new Periodic Table, and a compound of a metal selected from among palladium, platinum, rhodium and nickel each belonging to any of group 8 to group 10 of the new Periodic Table.

4. The process for producing adamantanol and adamantanone according to claim 1 , wherein hydrogen is added to reactants as an activating agent for oxygen molecules.
