What is Triphenylbismuth?

Description

Triphenylbismuth is a polymerization catalyst frequently used as an additive in dental and medical devices that may remain in the body so that the implants can be seen by X-ray.

Chemical properties

white to off-white crystalline powder

The Uses of Triphenylbismuth

Triphenylbismuth, as an volatile organometallic used in the preparation of thin films of superconducting oxides by CVD. It is also added to the fuel of rocket as cruing agent. It acts as a solidifying catalyst for butyl hydroxyl propellants.

Purification Methods

Dissolve it in EtOH, precipitate it with H2O, extract with Et2O, dry and evaporate till the residue crystallises. It has been recrystallised from EtOH and Et2O/EtOH and is a stable compound.
