Taw qhia
Triphenylphosphine yog ib qho organophosphorus compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm triphenylphosphine:
Zoo:
1. Cov tsos mob: Triphenylphosphine yog dawb mus rau daj crystalline los yog hmoov hmoov.
2. Solubility: Nws yog zoo soluble nyob rau hauv non-polar solvents xws li benzene thiab ether, tab sis insoluble nyob rau hauv dej.
3. Stability: Triphenylphosphine yog qhov ruaj khov ntawm chav tsev kub, tab sis nws yuav oxidize nyob rau hauv lub zog ntawm oxygen thiab noo noo nyob rau hauv cov huab cua.
Siv:
1. Ligand: Triphenylphosphine yog ib qho tseem ceeb ligand hauv kev sib koom tes chemistry. Nws tsim complexes nrog hlau thiab yog dav siv nyob rau hauv cov organic synthesis thiab catalytic tshua.
2. Tus neeg sawv cev txo qis: Triphenylphosphine tuaj yeem siv los ua tus neeg saib xyuas kom txo tau cov carbonyl tebchaw hauv ntau yam tshuaj lom neeg.
3. Catalysts: Triphenylphosphine thiab nws cov derivatives feem ntau yog siv los ua ligands rau kev hloov cov hlau catalysts thiab koom nrog cov organic synthesis tshua.
Txoj kev:
Triphenylphosphine feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm hydrogenated triphenylphosphonyl los yog triphenylphosphine chloride nrog sodium hlau (los yog lithium).
Cov Ntaub Ntawv Kev Nyab Xeeb: Cov khoom siv tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav yuav tsum hnav.
2. Tsis txhob kov cov oxidants thiab cov kua qaub uas muaj zog, uas yuav ua rau muaj kev phom sij txaus ntshai.
3. Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, qhov cua, kom deb ntawm cov khoom siv tsis zoo thiab qhov hluav taws kub.
