Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a device for preparing a deuterated electrolyte solvent. Background Art

[0002] Deuterated electrolyte solvents generally refer to solvents containing deuterium instead of ordinary hydrogen used in nuclear magnetic resonance spectroscopy analysis. Deuterated water, also known as heavy water, is one of the most common deuterated solvents. It is composed of deuterium and oxygen with a chemical formula of D2O. It is used as a solvent in NMR analysis and is particularly suitable for the analysis of biological macromolecules such as proteins and nucleic acids.

[0003] In the preparation of deuterium gas, heavy water is generated by electrolysis of water. In the process of electrolysis of water, oxygen is generated at the positive electrode and hydrogen is generated at the negative electrode. After the oxygen and hydrogen are generated, they combine in space to generate water, which affects the generation of heavy water and thus affects the generation efficiency of deuterium gas.

[0004] Therefore, we propose a device for preparing deuterated electrolyte solvents, which is conducive to the effective diversion of oxygen and hydrogen produced by the positive and negative electrodes, avoiding the combination of hydrogen and oxygen affecting the formation of heavy water and thus affecting deuterium, and is conducive to the collection and utilization of hydrogen and oxygen.
