Triphenylphosphine: ib tug tswv cuab ntawm tertiary phosphines
Triphenylphosphine (TPP) yog ib tug tswv cuab ntawm tertiary phosphines, uas yog phosphane, uas peb cov hydrogens raug hloov los ntawm phenyl pawg. Nws muaj lub luag haujlwm ua tus neeg sawv cev txo qis thiab NMR tshuaj hloov pauv siv. Nws yog ib qho ligand tseem ceeb siv hauv Wittig tshuaj tiv thaiv rau alkene synthesis. Cov tshuaj tiv thaiv no cuam tshuam nrog kev tsim cov alkyliden-etriphenylphosphoranes los ntawm kev ua ntawm butyllithium lossis lwm lub hauv paus ntawm quarternary halide. Triphenylphosphine yog siv los tsim cov organic compounds vim nws cov nucleophilicity thiab txo qis tus cwj pwm.

Kev Siv
Triphenylphosphine yog thawj sulfonated nrog oleum los tsim cov trisulfonic acid.
Triphenylphosphine siv tau rau hauv Wittig synthesis. Nws yog ib qho ligand txheem hauv homogeneous catalysis.
Triphenylphosphine yog siv rau hauv kev tsim cov organophosphorus intermediate, trimethyl phosphite hauv ester exchange method. Thiab tom qab ntawd ntau cov tshuaj tua kab organophosphorus xws li dichlorvos, monocrotophos thiab phosphamidon tuaj yeem tau txais ntxiv.
Tsis tas li ntawd xwb, nws siv tau ua cov stabilizers hauv kev tsim cov roj hmab thiab cov resins, cov tshuaj antioxidants hauv polyvinyl chloride, thiab cov khoom siv raw hauv kev tsim cov alkyd resins thiab polyester resins.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Nws tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
