Triphenylphosphine: setho sa li-phosphine tse phahameng
Triphenylphosphine (TPP) ke setho sa li-phosphine tse tharo, e leng phosphane, moo li-hydrogen tse tharo li nkeloang sebaka ke lihlopha tsa phenyl. E na le karolo e le moemeli oa ho fokotsa le motsoako oa referense ea phetoho ea lik'hemik'hale oa NMR. Ke ligand ea bohlokoa e sebelisoang karabelong ea Wittig bakeng sa tlhahiso ea alkene. Karabelo ena e kenyelletsa ho thehoa ha alkyliden-etriphenylphosphoranes ho tsoa ketsong ea butyllithium kapa motheo o mong holim'a halide ea quarternary. Triphenylphosphine e sebelisetsoa ho kopanya metsoako ea lintho tse phelang ka lebaka la nucleophilicity ea eona le mofuta oa eona oa ho fokotsa.

Tšebeliso
Triphenylphosphine e qala ka ho tšeloa sulfonate ka oleum ho etsa trisulfonic acid.
Triphenylphosphine e ka sebediswa tlhahisong ya Wittig. Ke ligand e tloaelehileng ho catalysis e tshwanang.
Triphenylphosphine e sebediswa ho etseng motsoako wa organophosphorus, trimethyl phosphite ka mokgwa wa phapanyetsano ya ester. Ebe letoto la dibolaya-dikokwanyana tsa organophosphorus tse kang dichlorvos, monocrotophos le phosphamidon di ka fumanwa hape.
Ho phaella moo, e ka sebediswa e le di-stabilizers ho kopantsweng ha rabara le di-resin, di-antioxidants ho polyvinyl chloride, le thepa e tala ho kopantsweng ha di-resin tsa alkyd le di-resin tsa polyester.
Ho paka le ho Romela
25KG/Moropa kapa ho ya ka ditlhoko tsa bareki.
E ka fana ka metsi ka leoatle le moea
Boloka le ho boloka
Nako ea ho boloka: Likhoeli tse 24 ho tloha letsatsing la tlhahiso ka har'a sephutheloana sa pele se sa buloang se bolokiloe sebakeng se pholileng se omileng se se nang khanya ea letsatsi, metsi.
Ntlo ea polokelo e nang le moea o kenang, Ho omisa mocheso o tlase, E arotsoe ho li-oxidant, li-acid.
