i-catalyst TPB Triphenyl Bismuth CAS 603-33-8
I-Triphenyl Bismuth
Izinga eliphezulu: GJB 5276-2003
I-CAS RN: 603-33-8
1. Izakhiwo zomzimba nezamakhemikhali:
1.1 Ifomula yama-molecule: C18H15Bi
1.2 Isisindo sama-molecule: 440.3
1.3 Ukuncibilika: Akuncibiliki emanzini, kodwa kuncibilikiswe ku-anhydrous alcohol kanye ne-n-heptane.
1.4 Ukuqina kanye nokusabela: Kuzinzile ekushiseni okuvamile kanye nokucindezela, kodwa kuphendula ngomswakama, i-oxidant enamandla kanye nokukhanya okunamandla kwe-ultraviolet.
Isikhuthazi sokwelapha esiphehlayo
I-Triphenylphosphonium (TPB) isetshenziswa njengesikhuthazi sokupholisa ama-propellants e-hydroxy anezinga eliphezulu lokusha. I-TPB inganciphisa izinga lokushisa lokupholisa le-propellant futhi ifinyeze isikhathi sokupholisa, futhi ayinawo umphumela omubi esicini sokucubungula kanye nezakhiwo zemishini. Umthamo obhekiselwe ku-TPB ungu-0.006%-0.05% we-propellant iyonke, kanti isikhathi sokupholisa singama-50 °C. Izinsuku eziyi-7
I-catalyst ye-polymerization ye-Monomer
Isetshenziswa njengesikhuthazi sokwenza i-acetylene ibe yi-cyclooctane tetratin, isikhuthazi sokwenza i-formaldehyde polymerization, i-ejenti yokwelapha ye-polycyclochloride, isikhuthazi sokwenza i-polymerization yezinye i-monomers, njll.
