Directory Guidance on Diethylzinc
Product Introduction:
Diethylzinc is a colorless, transparent organic zinc compound with a pungent odor, characterized by high reactivity and pyrophoricity.
The physical properties of diethylzinc include a density of 1.205g/cm³, a melting point of -28℃, a boiling point of 98℃, and a refractive index of 1.498 (at 20℃); it is readily soluble in saturated aliphatic and aromatic hydrocarbons. Diethylzinc undergoes hydrolysis in water to form zinc oxide and ethane, does not react with CO2 or ester groups, but can react with aldehyde and ketone compounds.
Diethylzinc is harmful to the body if ingested, inhaled, or absorbed through the skin, and it has a strong irritating effect on the eyes, skin, and mucous membranes.
Diethylzinc is pyrophoric in air, producing white zinc oxide smoke when burned. It reacts violently with water and decomposes to release flammable ethane gas, which can ignite. Therefore, it should be stored in a cool, well-ventilated warehouse, away from sources of ignition and heat.
In summary, diethylzinc is a highly reactive organometallic compound with properties of pyrophoricity and hydrolysis, thus requiring special safety measures during storage and use.

What Are The Uses of Diethylzinc
Product service:
As an important organometallic compound, Diethylzinc CAS 557-20-0 demonstrates its unique application value and potential in various fields. From organic synthesis to the semiconductor industry, and from archival preservation to catalyst preparation, the application range of diethylzinc is extensive and its impact is profound.
1. Applications in organic synthesis:
In organic synthesis, diethylzinc mainly serves as a provider of carbon negative ions and participates in various organic reactions. Due to its moderate reactivity, it can selectively perform addition reactions on unsaturated bonds such as carbonyl groups to generate alcohol compounds.
For example, under anhydrous conditions, the reaction between Diethylzinc and benzaldehyde can almost quantitatively generate alcohols with high optical purity (94% ee) of the product. In addition, Diethylzinc can undergo addition reactions with unsaturated bonds to form ternary ring compounds, which have unique value in the synthesis of specific organic molecules. These characteristics make Diethylzinc an important reagent for synthesizing complex organic molecules.
2. Applications in the semiconductor industry:
In the semiconductor industry, diethylzinc is a key material used in the metal organic chemical vapor deposition (MOCVD) process for growing high-quality, single crystal thin films.
It serves as a P-type dopant in the manufacturing of light-emitting diodes (LEDs), adjusting the electrical properties of semiconductor materials and optimizing device performance by precisely controlling the flow rate and proportion of dopants. The high purity and good volatility of Diethylzinc play a crucial role in the preparation of compound semiconductor materials, especially in the preparation of materials such as ZnSe and ZnS.
3. Application in deacidification agents:
Diethylzinc is also used as a deacidification agent for archival documents, which can effectively neutralize acidic substances in paper and extend the lifespan of paper archives. It reacts with acidic substances in paper to generate slightly alkaline zinc oxide, preventing paper from becoming acidic.
During this process, Diethylzinc not only neutralizes the acid in the paper, but also inhibits cellulose hydrolysis by reacting with cellulose hydroxyl groups, improving the strength and durability of the paper. Despite strict usage conditions, Diethylzinc provides an effective solution for specific archival protection work.
4. Application in catalysts:
Diethylzinc has high activity and can be used as an organic synthesis catalyst and polymerization reaction catalyst for the production of high molecular weight polymers such as polyethylene oxide. It acts as a catalyst in olefin polymerization reactions, promoting the progress of polymerization reactions, improving the efficiency of polymerization reactions and the quality of products.
In addition, Diethylzinc can also be used as a raw material, intermediate, and applied in the field of organic synthesis, as well as in demand in fields such as electronics, new materials, solar energy, chemical engineering, and pharmaceuticals.
In summary, the application of Diethylzinc covers multiple aspects from basic scientific research to industrial production, and its unique chemical properties and reactivity make it play an irreplaceable role in various fields. With the deepening of research on Diethylzinc, its potential for future applications and market value will further emerge.
Storage safety precautions:
Diethylzinc is a highly reactive organic metal compound that is extremely sensitive to air and moisture, so special attention needs to be paid to storage safety.
1. Storage conditions:
Diethylzinc should be stored at low temperatures of 0-6 ° C to slow down its possible decomposition reactions. The container must be kept sealed and stored under nitrogen protection to prevent reaction with oxygen and water vapor in the air.
2. Fire and explosion prevention:
Due to its flammability and spontaneous combustion in air, Diethylzinc must be kept away from sources of fire, heat, and sparks. The storage area shall be equipped with appropriate fire-fighting equipment, such as dry powder fire extinguishers. It is prohibited to use water or foam fire extinguishers.
3. Container handling:
Even if the container is empty, it should be handled with care as residual vapors may still be flammable. Tools that do not generate sparks should be used, and grounding or bridging should be ensured during handling and transfer to prevent electrostatic discharge.
4. Personal protection:
Operators should wear appropriate personal protective equipment, including chemical resistant work clothes, protective goggles, chemical resistant gloves, and be equipped with eye wash stations and safety showers in emergency situations.
5. Environmental control:
The storage area should maintain good ventilation to reduce the accumulation of flammable vapors and prevent vapor leakage into the work area.
6. Incompatible materials:
Diethylzinc should not come into contact with substances such as bases, halogens, metal salts, oxidants, and water, as these substances can cause violent reactions.
7. Waste disposal:
The waste disposal of Diethylzinc should comply with local and national regulations, and should not be discharged into sewers or the environment at will. Professional incineration treatment should be carried out.
8. Safety information:
Diethylzinc’s Safety Data Sheet (SDS) provides detailed safety information, including exposure controls, personal protective equipment, physical and chemical properties, stability, and reactivity. Operators should carefully read and comply with it.
In summary, the storage of Diethylzinc requires strict adherence to specific security measures to ensure personnel safety and environmental protection. Any violation of these safety measures may lead to serious safety accidents.
