Abstract
A process for the preparation of a deuterated compound, which requires neither many steps nor an expensive reagent, and is considerably economical and can be widely used for general-purposes because raw materials which can be used therein are not particularly limited. Specifically, a deuterated compound is obtained by a process comprising treating an organic compound (an aliphatic or alicyclic compound, an aromatic hydrocarbon or a polymer compound such as rubbers and proteins) in heavy water under high-temperature and high-pressure conditions not less than the subcritical temperature and the subcritical pressure.
