Triphenylphosphine: membala wa ma phosphine apamwamba
Triphenylphosphine (TPP) ndi membala wa ma tertiary phosphine, omwe ndi phosphane, momwe ma hydrogen atatuwa amalowetsedwa m'malo ndi magulu a phenyl. Ili ndi gawo lochepetsa komanso NMR chemical shift reference compound. Ndi ligand yofunika kwambiri yomwe imagwiritsidwa ntchito mu Wittig reaction popanga alkene. Izi zimaphatikizapo kupangidwa kwa alkyliden-etriphenylphosphoranes kuchokera ku butyllithium kapena maziko ena pa quarternary halide. Triphenylphosphine imagwiritsidwa ntchito popanga ma organic compounds chifukwa cha nucleophilicity yake komanso khalidwe lake lochepetsa.

Kagwiritsidwe Ntchito
Triphenylphosphine imayikidwa koyamba ndi oleum kuti ipange trisulfonic acid.
Triphenylphosphine ingagwiritsidwe ntchito popanga Wittig. Ndi ligand yokhazikika mu catalysis yofanana.
Triphenylphosphine imagwiritsidwa ntchito popanga organophosphorus intermediate, trimethyl phosphite mu njira yosinthira ester. Kenako mndandanda wa mankhwala ophera tizilombo a organophosphorus monga dichlorvos, monocrotophos ndi phosphamidon ungapezekenso.
Kuphatikiza apo, ingagwiritsidwe ntchito ngati zokhazikika popanga mphira ndi ma resini, ma antioxidants mu polyvinyl chloride, ndi zinthu zopangira popanga ma resini a alkyd ndi ma resini a polyester.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ikhoza kuperekedwa ndi nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
