MSDS for Deuterium
@ 70 F
Deuterium is used in tracer applications, in reaction rate studies, and exchange reaction studies, i.e., reactions in which one or more deuterium atoms trade places with light hydrogen atoms in some ion or molecule.
(D, or 2H), also called HEAVY HYDROGEN, isotope of hydrogen with atomic weight of approximately 2. Its nucleus, consisting of one proton and one neutron, has double the mass of the nucleus of ordinary hydrogen. Deuterium is a stable atomic species found in natural hydrogen compounds to the extent of 0.014 to 0.015 percent.
Deuterium was discovered (1931) by the American chemist Harold C. Urey (for which he was awarded the Nobel Prize for Chemistry in 1934) and his associates F.G. Brickwedde and G.M. Murphy. Urey predicted a difference between the vapour pressures of molecular hydrogen (H
Deuterium enters into all chemical reactions characteristic of ordinary hydrogen, forming equivalent compounds. Deuterium, however, reacts more slowly than ordinary hydrogen, a criterion that distinguishes the two forms of hydrogen. Because of this property, among others, deuterium is extensively used as an isotopic tracer in investigations of chemical and biochemical
The nuclear fusion of deuterium atoms or of deuterium and the heavier hydrogen isotope, tritium, at high temperature is accompanied by release of an enormous amount of energy; such reactions have been used in thermonuclear weapons. Since 1953, the stable solid substance lithium deuteride (LiD) has been used in place of both deuterium and tritium.
