Propellant medendi catalyst
Triphenylphosphonium (TPB) ut catalysta sanans adhibita est ad ratem altam ardentem sedylatam hydroxy propellentes. TPB sanationem temperationis propellentis et temporis sanationis minuere potest, et adversam effectum non habet in proprietatibus processus et proprietatibus mechanicis. Relatio dosis TPB est 0.006%-0.05% totius propellentis, et tempus sanationis 50 °C est. VII diebus
Monomer polymerization sedibus
Usus est catalysta pro polymerizatione acetylenae in cyclooctane tetratino, formaldehyde polymerizatione catalysto, agente curante polycyclochloride, catalysta pro polymerizatione monomerorum aliorum, etc.
