氘气-D2 - Physico-chemical Properties
Use | Deuterium, also known as heavy hydrogen, is a colorless, odorless, non-toxic combustible gas at normal temperature and pressure, and is a stable isotope of ordinary hydrogen. It contains 0.0139% to 0.0157% of the hydrogen in normal water. Its chemical properties are exactly the same as ordinary hydrogen. However, the reaction speed is smaller due to the high quality. Mainly used for special light bulbs, nuclear research, deuterium accelerator bombardment particles, tracers, etc. |
氘气-D2 - Introduction
Deuterium gas (D2) is an isotope of hydrogen in which a proton is replaced by a neutron. It is a colorless, tasteless, and odorless gas that is about 2 times denser than ordinary hydrogen (H2). 782-39-0 has some of the following properties:
1. Physical properties: 782-39-0 has a boiling point of -249.7 degrees Celsius and a melting point of -248.9 degrees Celsius. It is a gas state at room temperature, insoluble in water, alcohol and acid, but can react with some organic solvents such as ether and tetrahydrofuran.
2. Chemical properties: 782-39-0 participates in chemical reactions similar to ordinary hydrogen, but due to its large weight, it reacts slowly with other molecules or metals. It can be used as a hydrogen source and reducing agent to participate in a variety of organic synthesis reactions.
The main uses of the
782-39-0 are as follows:
1. Labeling reagent: 782-39-0 is usually used to label hydrogen atoms in organic molecules for nuclear magnetic resonance (NMR) studies. By replacing hydrogen atoms with deuterium atoms, more detailed information on the molecular structure, chemical environment and reaction kinetics can be provided.
2. synthetic chemistry: 782-39-0 can be used as a hydrogen source for some synthetic reactions. It participates in hydrogenation reactions, reduction reactions and proton transfer reactions, and is commonly used in the preparation of deuterated compounds, isotope-labeled compounds in organic synthesis and radioisotope-labeled compounds.
The common method for preparing 782-39-0 is to prepare heavy water (D2O) by electrolyzing aqueous sodium hydroxide solution, and then prepare deuterium gas by electrolyzing heavy water. The preparation and handling of deuterium gas requires special equipment and techniques, and the handling requires caution.
Note the following safety information when using and handling the 782-39-0:
1. 782-39-0 is a compressed gas, which should be stored in a special high-pressure gas container and comply with the relevant high-pressure gas safety operation regulations.
2. 782-39-0 has the risk of suffocation at high concentrations. It should be used in a well-ventilated place and avoid inhalation.
3.782-39-0 is explosive in oxygen or air, and contact with open flame and electric spark is prohibited.
4. Wear appropriate protective equipment such as goggles, gloves and laboratory goggles for safe operation.
5.782-39-0 has freezing properties, and care should be taken to avoid direct contact with the skin during handling.
Please note that when using and handling 782-39-0, you should follow relevant safety regulations and operating requirements, and operate in a suitable laboratory environment.
