whakakorikori TPB Triphenyl Bismuth CAS 603-33-8
Triphenyl Bismuth
Paerewa Whakahaere: GJB 5276-2003
CAS RN: 603-33-8
1. Ngā āhuatanga ā-tinana me te matū:
1.1 Tātai ngota: C18H15Bi
1.2 Taumaha ngota: 440.3
1.3 Wairewatanga: Kāore e wairewa i roto i te wai, engari ka wairewa i roto i te waipiro kore wai me te n-heptane.
1.4 Te pumau me te tauhohenga: Ka pumau i te pāmahana me ngā pēhanga noa, engari ka tauhohe ki te makuku, te waikura kaha me te mārama ultraviolet kaha.
Whakakōkī whakaora pūwero
Ka whakamahia te Triphenylphosphonium (TPB) hei whakakorikori whakaora mō ngā pūwero butylated hydroxy tere tahu. Ka taea e te TPB te whakaiti i te pāmahana whakaora o te pūwero me te whakapoto i te wā whakaora, ā, kāore he pānga kino ki te āhuatanga tukatuka me ngā āhuatanga miihini. Ko te horopeta tohutoro o te TPB he 0.006%-0.05% o te pūwero katoa, ā, ko te wā whakaora he 50 °C. 7 rā
Whakakōkī whakapūhui monomer
Whakamahia hei whakakorikori mō te whakapūhuitanga o te acetylene ki te cyclooctane tetratin, he whakakorikori whakapūhuitanga formaldehyde, he kaihoko whakaora mō te polycyclochloride, he whakakorikori mō te whakapūhuitanga o ētahi atu monomers, me ētahi atu.
