듀테리움 산화물 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid

용도

Deuterium Oxide is used to prepare specifically labelled isotopologs of organic compounds.

용도

To study chemical reaction rates and mechanisms. The cross section of deuterium for the capture of thermal neutrons is very low which makes it useful, in the form of heavy water, as a neutron moderator in nuclear reactors. Produces a considerable decrease in neutron energy per collision.

정의

deuterium oxide: Water in which hydrogen atoms, 1H,are replaced by the heavier isotopedeuterium, 2H (symbol D). It is acolourless liquid, which forms hexagonalcrystals on freezing. Its physicalproperties differ from those of ‘normal’water; r.d. 1.105; m.p. 3.8°C; b.p.101.4°C. Deuterium oxide, D2O, occursto a small extent (about 0.003%by weight) in natural water, fromwhich it can be separated by fractionaldistillation or by electrolysis. Itis useful in the nuclear industry becauseof its ability to reduce the energiesof fast neutrons to thermalenergies and because its absorptioncross-section is lower than that of hydrogenand consequently it does notappreciably reduce the neutron flux.In the laboratory it is used for labellingother molecules for studies ofreaction mechanisms. Water alsocontains the compound HDO.

Purification Methods

Distil it from alkaline KMnO4 [de Giovanni & Zamenhof Biochem J 92 79 1963]. NOTE that D2O invariably contains tritiated water and will therefore be RADIOACTIVE; always check the radioactivity level of D2O in a scintillation counter before using.
