Triphenyl Bismuth
Muyezo wa Executive: GJB 5276-2003
CAS RN: 603-33-8
1. Kapangidwe ka thupi ndi mankhwala:
1.1 Fomula ya molekyulu: C18H15Bi
1.2 Kulemera kwa Mamolekyulu: 440.3
1.3 Kusungunuka: Sisungunuka m'madzi, koma imasungunuka mu anhydrous alcohol ndi n-heptane.
1.4 Kukhazikika ndi kuchitapo kanthu: Kukhazikika pa kutentha kwabwinobwino ndi kupsinjika, koma kumakhudzana ndi chinyezi, okosijeni wamphamvu komanso kuwala kwamphamvu kwa ultraviolet.
Chothandizira chochiritsa chopangira mphamvu
Triphenylphosphonium (TPB) imagwiritsidwa ntchito ngati chothandizira kuchiritsa ma propellants a hydroxy omwe amayaka mofulumira kwambiri. TPB imatha kuchepetsa kutentha kwa propellant ndikufupikitsa nthawi yochiritsa, ndipo siili ndi vuto lililonse pa kapangidwe kake ndi mphamvu zake. Mlingo wofunikira wa TPB ndi 0.006%-0.05% ya propellant yonse, ndipo nthawi yochiritsa ndi 50 °C. Masiku 7
Chothandizira cha monomer polymerization
Amagwiritsidwa ntchito ngati chothandizira kupanga polymer ya acetylene kukhala cyclooctane tetratin, chothandizira kupanga polymer ya formaldehyde, chothandizira kuchiritsa polycyclochloride, chothandizira kupanga polymer ya ma monomers ena, ndi zina zotero.
