FA'ATULAGA:
Fa'amatalaga:
Triphenylphosphine: o se sui o phosphine tertiary
O le Triphenylphosphine (TPP) o se sui o le tertiary phosphines, o le phosphane lea, lea e suia ai hydrogens e tolu e vaega phenyl. E iai lona sao o se mea e fa'aitiitia ai le malosi ma se NMR chemical shift reference compound. O se ligand taua tele e fa'aaogaina i le tali a Wittig mo le fa'aputuina o alkene. O lenei tali e aofia ai le fausiaina o alkyliden-etriphenylphosphoranes mai le gaioiga a le butyllithium po'o se isi fa'avae i luga o le quarternary halide. E fa'aaogaina le Triphenylphosphine e fa'aputu ai mea fa'aola ona o lona nucleophilicity ma lona uiga fa'aitiitia.

Fa'aaogāga
E muamua fa'afefiloi le Triphenylphosphine ma le oleum e fausia ai le trisulfonic acid.
E mafai ona fa'aaogaina le Triphenylphosphine i le fa'asologa o Wittig. O se ligand masani i le homogeneous catalysis.
E fa'aaogaina le Triphenylphosphine i le fa'aputuina o se vaila'au fa'asolo o le organophosphorus, trimethyl phosphite i le metotia o le fesuia'iga o le ester. Ona mafai lea ona maua atili se fa'asologa o vaila'au fa'amate iniseti o le organophosphorus e pei o le dichlorvos, monocrotophos ma le phosphamidon.
E le gata i lea, e mafai ona faʻaaogaina o ni mea e faʻamautu ai i le gaosiga o le paʻu ma resins, antioxidants i le polyvinyl chloride, ma mea mata i le gaosiga o alkyd resins ma polyester resins.
Afifiina ma le Felauaiga
25KG/Palu po'o mana'oga o tagata fa'atau.
E mafai ona tilivaina i le vasa ma le ea
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.
