HANGANGA:
Whakaahuatanga:
Triphenylphosphine: he mema o ngā phosphine tuatoru
Ko te Triphenylphosphine (TPP) he mema nō ngā phosphines tuatoru, arā, ko te phosphane, e whakakapia ai ngā hauwai e toru e ngā rōpū phenyl. He mahi tāna hei kaiwhakaiti me te matū tohutoro nekehanga matū NMR. He ligand nui e whakamahia ana i roto i te tauhohenga Wittig mō te hanga alkene. Kei roto i tēnei tauhohenga te hanganga o ngā alkyliden-etriphenylphosphoranes mai i te mahi a te butyllithium, tētahi atu pūtake rānei i runga i te halide hauwhā. Ka whakamahia te Triphenylphosphine hei hanga i ngā matū waro nā tōna nucleophilicity me tōna āhua whakaiti.

Whakamahinga
Ka whakawhanawhanahia tuatahitia te Triphenylphosphine ki te oleum hei hanga i te waikawa trisulfonic.
Ka taea te whakamahi i te Triphenylphosphine i roto i te hanga Wittig. He ligand paerewa i roto i te whakakorikori ōrite.
Ka whakamahia te Triphenylphosphine hei hanga i tētahi takawaenga organophosphorus, arā, te trimethyl phosphite mā te tikanga whakawhiti ester. Kātahi ka taea te whiwhi anō i tētahi raupapa o ngā patupatu organophosphorus pērā i te dichlorvos, te monocrotophos me te phosphamidon.
Hei tāpiritanga, ka taea te whakamahi hei whakaū i roto i te hanganga rapa me ngā kapia, hei ārai mate i roto i te polyvinyl chloride, me te rauemi mata i roto i te hanganga o ngā kapia alkyd me ngā kapia polyester.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
