1. Iimpawu zomzimba kunye neekhemikhali:
1.1 Ifomula yemolekyuli: C18H15Bi
1.2 Ubunzima beMolekyuli: 440.3
1.3 Ukunyibilika: Ayinyibiliki emanzini, kodwa inyibilikiswe kutywala obuyi-anhydrous kunye ne-n-heptane.
I-1.4 Ukuzinza kunye nokusebenza kwakhona: Izinzile kwiqondo lokushisa eliqhelekileyo kunye noxinzelelo, kodwa isabela ngomswakama, i-oxidant enamandla kunye nokukhanya okunamandla kwe-ultraviolet.
I-propellant yokunyanga i-catalyst
I-Triphenylphosphonium (TPB) isetyenziselwa ukunyanga i-catalyst yezinga eliphezulu lokutshisa i-butylated hydroxy propellants. I-TPB inokunciphisa ukushisa okuphilisayo kwe-propellant kunye nokunciphisa ixesha lokunyanga, kwaye ayinayo impembelelo embi kwipropathi yokucubungula kunye neepropati zomatshini. Idosi yereferensi ye-TPB yi-0.006%-0.05% ye-propellant iyonke, kwaye ixesha lokunyanga yi-50 °C. Iintsuku ezisi-7
I-Monomer polymerization catalyst
Isetyenziswe njenge-catalyst ye-polymerization ye-acetylene kwi-cyclooctane tetratin, i-formaldehyde polymerization catalyst, i-agent yokunyanga i-polycyclochloride, i-catalyst ye-polymerization yezinye iimonomers, njl.
