Taw qhia
Ethyltriphenylphosphine bromide, tseem hu ua Ph₃PCH₂CH₂CH₃, 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 ethyltriphenylphosphine bromide:
Zoo:
Ethyltriphenylphosphine bromide yog xim tsis muaj xim rau lub teeb daj daj lossis kua nrog lub zog benzene aroma. Nws yog soluble hauv cov kuab tshuaj organic xws li ethers thiab hydrocarbons ntawm chav tsev kub. Nws muaj qis solubility dua dej.
Siv:
Ethyltriphenylphosphine bromide muaj ntau yam kev siv hauv cov organic synthesis. Nws ua raws li phosphorus reagent rau nucleophilic hloov pauv ntawm halogen atoms thiab nucleophilic ntxiv cov tshuaj tiv thaiv ntawm carbonyl compounds. Nws tseem tuaj yeem siv los ua ligand rau organometallic chemistry thiab kev hloov pauv hlau-catalyzed cov tshuaj tiv thaiv.
Txoj kev:
Ethyltriphenylphosphine bromide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv hauv qab no:
Ph₃P + BrCH₂CH₂CH₃ → Ph₃PCH₂CH₂CH₃ + HBr
Cov ntaub ntawv kev nyab xeeb:
Ethyltriphenylphosphine bromide muaj toxicity qis dua tab sis yuav tsum tau siv nrog ceev faj. Kev raug ethyltriphenylphosphine bromide tuaj yeem ua rau khaus thiab qhov muag puas. Kev ceev faj tsim nyog, xws li hnav hnab looj tes thiab looj tsom iav, yuav tsum tau ua thaum siv, thiab ua kom muaj cua zoo. Tsis txhob nqus nws cov vapors lossis nkag mus rau ntawm daim tawv nqaij thiab qhov muag thaum ua haujlwm.
