Useful:

• Chemical Classes: Metals -> Metals, Inorganic Compounds
• Canonical SMILES: [Tl]
• Recent NIPH Clinical Trials: Usefulness of FDG-PET/CT examination as prediction of effect of immune checkpoint inhibitors in patients with non-small cell lung cancer : a pilot study
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly.
• Effects of Short Term Exposure: Ingestion could cause effects on the gastrointestinal tract and nervous system. Ingestion could cause hair loss. Ingestion of large amounts could cause death. The effects may be delayed. Medical observation is indicated.

Technology Process of Thallium

There total 3 articles about Thallium 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:

thallium + hydrogen (1333-74-0) → thallium hydride (7440-28-0) + Tl2H2 + thallium trihydride (82391-14-8) + thallium dihydride (117439-42-6)

Guidance literature:

In gaseous matrix; H2 and Tl codeposited in solid hydrogen matrix at 3.5 K; detd. by IR;

DOI:10.1002/anie.200353216

Reference yield:

thallium + hydrogen (1333-74-0) → thallium hydride (7440-28-0) + thallium trihydride (82391-14-8) + HTlTlH (148084-69-9) + thallium dihydride (117439-42-6) + Tl2H2 (148084-69-9)

Guidance literature:

In solid matrix; Irradiation (UV/VIS); laser focused on Tl target; atoms co-deposited with H2 and Ne or Ar ontoCsI cooled to 3.5 K; irradiation by Hg arc or 193 nm laser; detn. by IR;

DOI:10.1021/jp0498973

Reference yield:

→ thallium hydride (7440-28-0)

Guidance literature:

upstream raw materials:

hydrogen
