Useful:

• Chemical Classes: Metals -> Beryllium Compounds, Inorganic
• Canonical SMILES: [Be]
• Recent ClinicalTrials: Treatment of N-methyl-D-aspartate (NMDA) Enhancers for Schizophrenia
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is irritating to the respiratory tract. Inhalation of dust or fume may cause chemical pneumonitis. The effects may be delayed. Medical observation is indicated. Exposure could cause death.
• Effects of Long Term Exposure: Sensitization to the substance, through repeated or prolonged inhalation or skin contact, may result in serious granulomatous lung disease (chronic beryllium disease). This substance is carcinogenic to humans.

Technology Process of Beryllium

There total 60 articles about Beryllium 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:

synthetic route:

Reference yield: 36.0%

beryllium(II) chloride (7787-47-5) → beryllium (14390-89-7,13966-02-4,7440-41-7)

Guidance literature:

With sodium; in a steel bomb; 24% oxide;

Reference yield: 33.0%

beryllium(II) fluoride → beryllium (14390-89-7,13966-02-4,7440-41-7)

Guidance literature:

With sodium fluoride; Electrolysis; molar ratio of NaF : BeF2 = 1:2; molten state; nickel cathode (melting pot), carbon anode; 7-10A at 15V (av. of 2.5h); (After 2.5 h anode effect hindered the process!); milling; washing (water, ammonia); cetrifuging; washing (ethylene bromide + alc., D=1.95);

Reference yield: 13.0%

NaF*BeF2 → beryllium (14390-89-7,13966-02-4,7440-41-7)
