Kaaliyayaasha daaweynta dabaysha
Triphenylphosphonium (TPB) waxaa loo isticmaalaa sidii kiciye daaweyn ah oo loogu talagalay butylated hydroxy propellants oo heer sare ah oo gubasho ah. TPB waxay yareyn kartaa heerkulka bogsashada ee propellant-ka waxayna gaabin kartaa waqtiga bogsashada, mana laha saameyn xun oo ku saabsan hantida farsamaynta iyo sifooyinka farsamada. Qiyaasta tixraaca ee TPB waa 0.006%-0.05% wadarta propellant-ka, waqtiga bogsashadana waa 50 °C. 7 maalmood
Monomer polymerization catalyst
Waxaa loo isticmaalaa sidii kicinta polymerization-ka acetylene ee loo beddelo tetratin cyclooctane, kicinta polymerization formaldehyde, wakiilka daaweynta polycyclochloride, kicinta polymerization-ka ee monomers-ka kale, iwm.
