Use of deuterium gas
Deuterium gas is widely used. It is not only used in nuclear energy, controllable nuclear fusion reaction, lasers, light bulbs, experimental research, semiconductor material toughening treatment, nuclear medicine and agriculture, but also has some important military applications, such as manufacturing hydrogen bombs, neutron bullets and DF laser weapons.
Hydrogen lamp and deuterium lamp are common light sources in the ultraviolet region. They produce continuous radiation in the wavelength range of 180~375nm. Under the same operating conditions, the emission intensity of deuterium lamp is about 4 times greater than that of hydrogen lamp. The glass has strong absorption to the radiation within this wavelength range, so the quartz light window must be used.
Deuterium gas is one of the important ways and sources to produce deuterium reagent, which is also the necessary solvent for nuclear magnetic resonance (NMR) instruments used in analysis and detection experiments. Deuterated reagents are used to avoid the interference of hydrogen atoms in common solvents, so as to accurately analyze the proportion of hydrogen elements in organic molecules. They play an important and irreplaceable role in the detection and judgment of organic molecular structure in pharmaceutical chemistry.
Due to the significant difference in atomic mass between deuterium and hydrogen, the bond formed by carbon and deuterium will vibrate at a lower frequency, and its zero basic energy is lower than the corresponding hydrocarbon bond energy, and their transition state activation energy is similar. Therefore, breaking the carbon deuterium bond requires more energy than breaking the hydrocarbon bond. (in short, the "survival" of carbon deuterium bonds requires less energy than that of hydrocarbon bonds, and greater "power" is required to disassemble the combination of carbon and deuterium.). Just because it takes more energy to break the carbon deuterium covalent bond than the hydrocarbon bond, when the hydrogen in the compound is replaced by deuterium, the rate of chemical reaction will be significantly slowed down. If the transition state of the reaction involves the symmetric fracture of the hydrocarbon bond, the hydrogen on the hydrocarbon bond can be replaced by deuterium, which can slow down the reaction rate by about 85%. Theoretically, if the breaking of the hydrocarbon bond involves the rate determining step of the metabolic pathway, the metabolic process of its deuterated compounds catalyzed by metabolic enzymes in the organism will slow down or stop after hydrogen is replaced by deuterium.
With the development of science and technology, deuterium will be used more and more widely, and the demand and Research on Deuterium will become more and more important.
