• Description: Diethyl zinc is an organometal compound and is a dangerous fire hazard. It spontaneously ignites in air and reacts violently with water, releasing flammable vapors and heat. It is a colorless, pyrophoric liquid with a specific gravity of 1.2, which is heavier than water, so it will sink to the bottom. It decomposes explosively at 248°F (120°C). It has a boiling point of 243°F (117°C), a flash point of ?20°F (?28°C), and a melting point of ?18°F (?27°C). The four-digit UN identification number is 1366. The NFPA 704 designation is health 3, flammability 4, and reactivity 3. The white space at the bottom of the diamond has a W with a slash through it to indicate water reactivity. Primary uses of diethyl zinc are in the polymerization of olefins, high-energy aircraft, and missile fuel and in the production of ethyl mercuric chloride.
• Uses: In organic synthesis; in preservation on archival papers. Diethyl zinc is used in organic synthesis. It isalso used in preservation of archival papers. Diethylzinc solution can be used in the synthesis of:Bis(pyridylpyrrolyl)zinc luminescent complexes.A versatile building block, 5-(ketoaryl)thiazole.ZnxCd1-xSe nanocrystals having high luminescence properties.

Technology Process of Diethylzinc

There total 44 articles about Diethylzinc which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
