Patent ID: 8093422

Claim:
A method for deuteration of an aromatic ring comprising: reacting the aromatic ring under a neutral condition with a deuterated solvent that is neither deuterium peroxide (D 2 O 2 ) nor supercritical D 2 O in the presence of only one activated catalyst under non-supercritical condition, wherein the aromatic ring may have at least one substituent and is at least one selected from the group consisting of benzene, naphthalene, anthracene, phenanthrene, 9,10-dihydroanthracene, naphthacene, pentaphene, pentacene, hexaphene, hexacene, heptaphene, heptacene, trinaphthylene, 1,4-dihydronaphthalene, pyrene, triphenylene, biphenylene, indene, indan, indacene, phenalene, fluorene, acenaphthene, acenaphthylene, fluoranthene, tetraphenylene, coranthrene, acephenanthrylene, aceanthrylene, cyclopentaphenanthrene, chrysene, picene, pleiadene, rubicene, pyranthrene, coronene, perylene, rubrene, dibenzophenanthrene, 1,2-dibenzo-1,3-cycloheptadiene and ovalene, the reaction is carried out at 180° C. or lower, and the only one activated catalyst is activated platinum carbon and is activated with hydrogen or heavy hydrogen gas.
