• Canonical SMILES: [Sb]
• Recent ClinicalTrials: Evaluating the Safety and Efficacy of SB Injection in Patients With Advanced or Primary Hepatocellular Carcinoma (HCC)
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: May cause mechanical irritation to the eyes.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis especially when the skin is exposed to fumes. The substance may have effects on the lungs. This may result in pneumoconiosis.
• Uses: Has been used as fumigating agent. Stibine is used as a fumigating agent.Although the commercial application of thiscompound is limited, an exposure risk mayarise when it is formed as a result ofmixing an antimony compound with a strongreducing agent in the presence of acid.

Technology Process of Antimony

There total 12 articles about Antimony 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: 20.0%

methylantimondichloride (42496-23-1) → stibane (7803-52-3) + methylstibine (23362-09-6)

Guidance literature:

With lithium aluminium tetrahydride; In dibutyl ether; by addn. of CH3SbCl2 dropwise at -40°C to suspension of LiAlH4 in dibutyl ether; warming to room temp., collecting the volatile products in traps (CH3SbH2 at -98°C);

Reference yield:

sodium tetrathioantimonate(V) + magnesium (7439-95-4) → antimony (7440-36-0) + stibane (7803-52-3) + hydrogen sulfide (7783-06-4)

Guidance literature:

reaction at absence of base; formation of small amounts of SbH3 in the heat;;

Reference yield:

antimony(III) chloride (10025-91-9) + magnesium (7439-95-4) → antimony (7440-36-0) + stibane (7803-52-3)

Guidance literature:

With ethanol; in cold; few drops of ethanol;

upstream raw materials:
