Triphenyl Bismuth

Executive standard: GJB 5276-2003

CAS RN: 603-33-8

1. Physical and chemical properties:

1.1 Molecular formula: C18H15Bi

1.2 Molecular Weight: 440.3

1.4 Solubility: Insoluble in water, but dissolved in anhydrous alcohol and n-heptane.

1.5 Stability and reactivity: Stable at normal temperature and pressures, but reacts with moisture, strong oxidant and strong ultraviolet light.

2. Technical indexes:

Item	Index
Purity,%	≥97.5
Melting point,℃	≥77.0
Bi content.%	47.0-47.9
Insoluble in acetone content,%	≤0.10
Mg content,%	≤0.003
Total halogen content(in Cl),%	≤0.05
Appearance	White or milky crystal, no visible impurities

3. Uses: Triphenyl bismuth (TPB) has been used as the curing catalyst of HTPB propellant. TPB could decrease curing temperature and reduce curing time of the propellant, as well as it has no damaging effect on the performance and mechanics properties. The dosage of TPB is 0.006%-0.05% of total weight for the propellant. Curing time is a week in 50℃. TPB can be also used as the catalyst of the polymerization for ethyne into cyclooctatraene, formaldehyde, the curing agent for polycyclochlorides, and other monomers etc.

4. Safety instructions: Toxic by ingestion and inhalation. Eye and skin contact can cause inflammation. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.
